Patent Application
20230236853
Various security products are available to provide control over data travel in cloud applications and subscription services accessed via the Internet. When a client device requests a resource from a server, a proxy server may enforce policies, detect threats, and provide governance actions with respect to the request. In one example, Microsoft® Cloud App Security (MCAS) is available for monitoring Microsoft® Office 365® subscription-based services.
In some security services, there may be an additional level of monitoring activities for websites or online applications. For example, the first level of monitoring may be performed by a proxy server. A second level may include a client side monitoring system that functions within a browser on a client device. The client side monitoring system may dynamically monitor certain activities that are client based or created by a browser, which cannot be seen by the server. The browser may perform the client side monitoring, once a page is rendered, when a user attempts to perform an action that cannot be detected by the server.
A security system provider may want to offer its customers a way to monitor methods of exporting data from web pages. Part of this effort may include monitoring all resources that are being requested or dynamically generated in a web page. Some websites rely heavily on client side-based web page rendering that occurs once the page is loaded into the browser. For example, a business analytics web service may provide reports with charts based on collected data for viewing in an interactive user interface of a browser (e.g., Microsoft® Power BI®). The charts and reports may be rendered in the browser on the client device and there may be little or no HTML (hypertext markup language) code utilized for rendering and displaying of the reports. Client side monitoring and session control may occur within the rendering of a web page on a client device. However, such client side monitoring and governance processes may severely slow the performance of a user interface (UI) of the browser and web page rendering processes.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
Methods and systems are provided for enhanced exporting of data from web pages. In response to a request for data from a web page, browser cached data is checked for the requested data, and if present, the requested data is returned from the cache. If the requested data is not present in the browser cached data, the data is dynamically generated for return, and may be cached in the browser cached data for future data requests.
In one aspect, a browser in a client device comprising a script-code snippet manager configured to receive a user interface (UI) script-code snippet from a web page during a current session. The script-code snippet manager comprises a chain logic engine configured to determine whether an in-memory map indicates a stored output value of the UI script-code snippet generated by prior execution of the UI script-code snippet, and in response to determining the in-memory map does not indicate the stored output value of the UI script-code snippet, determine whether an in-local storage map for the browser indicates the stored output value of the UI script-code snippet generated by prior execution of the UI script-code snippet. In response to determining the in-local storage map does not indicate the output value of the UI script-code snippet, the script-code snippet manager is further configured to control execution of the UI script-code snippet for the current session to generate the output value of the UI script-code snippet, and store the output value in the in-memory map and in the in-local storage map.
The chain logic engine is further configured to, in response to determining the in-memory map does indicate the stored output value of the UI script-code snippet, return the output value of the UI script-code snippet from the in-memory map for use in the current session, or in response to determining the in-local storage map does indicate the output value of the UI script-code snippet, return the output value of the UI script-code snippet from the in-local storage map for use in the current session and storing the output value in the in-memory map.

Security products for cloud based applications and user subscription services may provide policy enforcement for data communication over a network (e.g., the Internet). When a client device requests a resource from a server, a proxy server may enforce policies, detect threats, and provide governance actions with respect to the request. In one example, Microsoft® Cloud App Security (MCAS) is available for monitoring Microsoft® Office 365® subscription-based services.
Some security products, or proxy servers, provide a man in the middle solution for service subscribers. Such services may monitor and control a user's access attempts and requests for resources (e.g., documents) from an online application (e.g., Microsoft® OneDrive®). The security service may reflect the application to the user's client device such that it appears the same in a user's browser as a direct access to the application on an application server. Prevention and detection monitoring may be performed by the proxy server on the user's interactions with the reflected application in order to apply policies and prohibit certain activities. The policies (e.g., session policies, download policies, upload policies, or policies for other types of activities) may be configured by a tenant administrator on a server device. Also, filters such as user agents may be configured for risky IDs or certain conditions. Once a user logs into a managed application, the security system may detect who the user is and which tenant they belong to, and apply polices configured for the user. For example, a user may access a Microsoft® OneDrive® account and connect work environment resources to OneDrive® in order to download a sensitive file to their client device. A real time session policy may indicate that a sensitive file cannot be downloaded to an unmanaged device. Once the user tries to download that file, a blocked-download notification may be generated according to the policy, which may notify the user that the file cannot be downloaded. However, if no download policy is configured in the proxy server, the user would be able to download the file.
In some security services, there may be an additional level for monitoring activities in websites or online applications. For example, the first level of monitoring may be performed by a proxy server, as described above, which can reflect static elements from the application server (e.g., hypertext markup language (HTML) pages and style resources, etc.). A second level of monitoring includes a client side monitoring system that functions within a browser on a client device. The client side monitoring system may dynamically monitor certain activities that are client-based or created by a browser, which cannot be seen by the server. The policies and filters used for the client side monitoring and policy enforcement may also be configured by a tenant administrator. The browser may perform the client side monitoring, once a page is rendered, when a user attempts to perform an action that cannot be detected by the server.
Some websites rely heavily on client side-based web page rendering that occurs once the page is loaded into the browser. For example, a business analytics web service may provide reports with charts based on collected data for viewing in an interactive user interface of a browser (e.g., Microsoft® Power BI®). The charts and reports may be rendered in the browser on the client device and there may be little or no HTML utilized for rendering and displaying the reports. Client side monitoring and session control may occur within the rendering of the web page on the client device for user interaction with the web page. However, such client side monitoring and governance processes may severely affect performance of the user interface (UI) of the browser and web page rendering.
The present disclosure provides embodiments for improving the performance of a user interface in a managed browser to allow for faster rendering and execution of web pages while performing client side monitoring and policy enforcement
A client side proxy policy system provides a way to monitor methods of exporting data from web pages including monitoring resources that are requested or dynamically generated in a web page. The browser-based, client side method leverages browser native support for caching data in order to improve proxy performance and generically support various applications. Client side processing actions often occur repeatedly in a browser. In the present disclosure, the result of web page processing actions are cached and used again without incurring processing latency to improve user interface performance.
In one example, during browser-based rendering, when a script-code snippet of a user interface (UI) is selected from a web page for execution, a chain of command searches through layers of memory for an output value from previously executing the UI script-code snippet. If the output value is found, it is used to generate the user interface. In this manner, speed of client side rendering of a user interface is improved. If the output value is not found in the memory layers, the browser controls execution of the UI script-code snippet to generate the output value and may save the output value in the layers of memory. The browser may execute the UI script-code snippet itself, or may decide to send it to a server for execution depending on the cost of the execution.
Embodiments of the present disclosure for improving performance in client side browser-based rendering of user interface script-code snippets may be implemented in various ways. For instance,
As shown in
Client device 102 is communicatively coupled to server device 104 and proxy server 106 (e.g., via a network or combination of networks, such as the Internet). Server device 104 is also communicatively coupled to proxy server 106. Client device 102, server device 104, and proxy server 106 may each comprise any suitable computing device, such as a stationary computing device (e.g., a desktop computer or personal computer), a mobile computing device (e.g., a Microsoft® Surface® device, a personal digital assistant (PDA), a laptop computer, a notebook computer, a tablet computer such as an Apple iPad™, a netbook, etc.), a mobile phone (e.g., a cell phone, a smart phone such as an Apple iPhone, a phone implementing the Google® Android™ operating system, a Microsoft Windows® phone, etc.), a wearable computing device (e.g., a head-mounted device including smart glasses such as Google® Glass™, Oculus Rift® by Oculus VR, LLC, etc.), a gaming console/system (e.g., Microsoft Xbox®, Sony PlayStation®, Nintendo Wii® or Switch®, etc.), an appliance, a set top box, etc.
Website 120 may be a website that provides web pages in response to requests from browser 108, where the requests comprise uniform resource locators (URL). In some embodiments, website 120 may be generated by a cloud based software application that may be provided through a subscription service (e.g., Microsoft 365®) and hosted by server device 104. However, the source of web site 120 is not limited and any suitable source may be utilized. A user may interact with website 120 directly or via proxy server 106 depending how system 100 is configured by a system administrator. In some embodiments, when a web session is initiated with website 120, the user may be authenticated, for example, by an identity provider of the website. The session may persist until website 120 and/or browser 108 are closed by the user or otherwise closed. In some embodiments, server device 104 and/or website 120 may be part of a data center that provides cloud services to multiple users or business organizations (e.g., tenants). A directory of the tenants may identify corresponding service instances (e.g., containers) that each include a tenant's items, such as users, domains, subscriptions, etc. Multitenancy of server device 104 may occur where several different cloud customers access the same computing resources. In this example, the system administrator may be a tenant administrator that may populate tenant configuration parameters 122 to define the users, domains, security policies, and other aspects of the software subscription of the tenant. The tenant administrator (or system administrator) may also configure security policy parameters 132 in proxy server 106 and/or browser security policy parameters 116 in client device 102.
The tenant configuration parameters 122 may indicate which users are to be monitored (or proxied) by proxy server 106 and/or browser 108. When a user that is monitored by proxy server 106 requests webpage 110 from website 120, the webpage may be sent to proxy server 106 to apply policies that are defined by security policy parameters 132. Monitored reflection generator 130 may or may not transmit web page 110 to client device 102 depending on security policy parameters 132. For example, the user may not have permission to download web page 110, or may not have permission to request certain actions via web page 110 (e.g., uploading data or a file to server device 104) based on the security policy parameters. In instances where proxy server 106 does not allow an action requested by a user, proxy server 106 is configured to transmit a notification to client device 102 for display by browser 108, to indicate the denial of the request and/or policy issues that may have caused the denial. In instances where the user has permission to access web page 110, monitored reflection generator 130 is configured to generate a reflection comprising web page 110 and send it to client device 102 where browser 108 is configured to build a web page document object model (DOM) and display web page 110 in a user interface as reflected from a domain of proxy server 106. Further attempted interactions between browser 108 and server device 104 may be monitored and governed by proxy server 106. In one example, a user may access a cloud application (e.g., in Microsoft® OneDrive®) on server device 104, which may be a work environment resource. The user may attempt to download a sensitive file to the managed client device 102. If the tenant administrator configured a real time session policy with security policy parameters 132, which indicate that the sensitive file could not be downloaded to the user's client device 102, proxy server 106 is configured to block the download operation and transmit a notification to browser 108 indicating that the user does not have permission to download the file.
However, much of web page 110 may comprise script-code that is rendered by browser 108 rather than server device 104 for generating a user interface or a portion of a user interface. For example, script-code snippet 112 may comprise a region of operative scripting language code (e.g., JavaScript code) that may perform a function or action in web page 110. UI script-code snippet 112 may be referred to as script code snippet 112. Browser 108 may be configured to render (i.e., execute) UI script-code snippet 112 and output user interface code (e.g., all or a region of web page 110) that can be displayed in a display device (not shown) of client device 102. Browser 108 may be configured to execute UI script-code snippet 112 in response to an event in web page 110 (e.g., a user input received via web page 110 to request a function or an action). Server device 104 may not be aware of actions or events triggered in web page 110, and actions or events may be handled solely by browser 108. For such operations, a second level of monitoring may be implemented within browser 108 according to browser security policy parameters 116. Browser security policy parameters 116 may be configured by the tenant administrator (or system administrator) and may define policies and filters used in client device 102 side monitoring and policy enforcement. The monitoring system of client device 102 may be configured to dynamically monitor certain activities initiated in browser 108. Browser 108 may be configured to perform the client side monitoring, once web page 110 is rendered.
In one example of client device 102 side monitoring, a user may attempt to copy and paste sensitive text from web page 110 to a document. This process may utilize a clipboard resource of client device 102. However, because the tenant administrator configured browser security policy parameters 116 to include a policy that does not allow clipboard actions for the user, the user's attempt is blocked and the user cannot extract or inject any sensitive data from or into web page 110. In this regard, clipboard actions may include browser based rendering of UI script-code snippet 112, where UI script-code snippet 112 is not rendered by server device 104. There is no interaction needed between client device 102 and server device 104 or proxy device 106 to perform the blocking of the copy and paste attempt. Instead, client device 102 is configured to perform client side monitoring and session control during the rendering of UI script-code snippet 112 by browser 108. However, such client side monitoring and governance processes may severely affect performance of generating a user interface (UI) in browser 108 based on the local rendering process.
Script-code snippet manager 114 is configured to provide an improved level of performance in generating a user interface in such a monitored web page 110 of browser 108, and also in unmonitored configurations of web page 110 of browser 108. The performance improvement method includes the repeated use of an output value for a user interface that is generated by a single execution of script-code snippet 112. The output value is utilized in one or more subsequent user interface generating processes in web page 110 by browser 108. For example, some rendering code flows (e.g., including UI script-code snippet 112) of browser 110 may be repeated over and over again when rendering web page 110 or when rendering different parts of web page 110 as a result of user input actions received via web page 110. The repeated code flows may occur during a single session of browser 108 or over multiple sessions (e.g., after web page 110 is closed and reloaded). A series of cacheable memory layers are configured to capture and return an executed UI script-code snippet 112 output value (i.e., a rendered UI script-code snippet 112 output value) for reuse in repeated user interface generating processes in web page 110.
In some embodiments, when script-code snippet 112 has been selected for a rendering process, script-code snippet manager 114 is configured to detect whether UI script-code snippet 112 has been previously executed. If it has previously been executed, script-code snippet manager 114 is configured to retrieve a stored output value of the previously executed script-code snippet 112 from one of the cacheable layers and use it to generate a user interface or a portion of a user interface of web page 110. The retrieved output value of UI script-code snippet 112 may be utilized to generate the user interface immediately, rather than having to first execute (or render) UI script-code snippet 112 and then generate the user interface. Using the retrieved output value repeatedly, may be much faster than having to execute the UI script-code snippet each time it is called. In this manner, the number of rendering processes and associated latency in a browser session, or in multiple sessions, may be reduced to the number of unique renderings, where repeated rendering processes are eliminated or reduced in number. For example, if a browser would normally render UI script-code snippet 112500 times in a session of browser 108, browser 108 is configured to take the time to execute UI script-code snippet 112 once, and store an output value of the execution. For the remaining 499 uses of UI script-code snippet 112, script-code snippet manager 114 is configured to respond to an event by retrieving the stored output value of script-code snippet 112 for use in generating a user interface in web page 110, and avoid the execution time latency.
During the browser-based rendering, for example, when UI script-code snippet 112 is selected for execution based on an event in web page 110, a chain of command of script-code snippet manager 114 may search through layers of memory until the output value from a previous rendering of script-code snippet 112 is found. If the output value is not found in the memory layers, script-code snippet manager 114 is configured to control execution of the script-code snippet to generate the output value for generating a user interface in web page 110 in response to the selection of UI script-code snippet 112 for execution. For example, browser 108 itself may respond by executing UI script-code snippet 112, or script-code snippet manager 114 is configured to decide to send UI script-code snippet 112 to server device 104 for execution, and server device 104 is configured to return the output of execution. Output of the execution of UI script-code snippet 112 by browser 108 or server device 104, in response to the selection of UI script-code snippet 112 for execution, may be used to generate a user interface of web page 110, and may be stored in the layers of memory for future use in generating the user interface of web page 110.
In embodiments, system 100 may operate in various ways to perform its functions. For example,
Flowchart 200 of
In step 204, it is determined whether an output value from a previous execution of the UI script-code snippet is stored in one or more layers of memory. For example, UI script-code snippet 112 may have been previously executed (i.e., rendered) for use in browser 108 and/or web page 110. Script-code snippet manager 114 may search for output from the prior execution of script code snippet 112 in one or more layers of memory of client device 102. Operation proceeds to step 206.
In step 206, in instances where an output value of a previous execution of the UI script-code snippet is found to be stored in the one or more layers of memory, the flow of steps proceeds to step 208. For example, the flow proceeds to step 208 when script-code snippet manager 114 finds that an output value of previous execution of UI script-code snippet 112 has been stored in the one or more layer of memory of client device 102.
In step 208, the output value of the previous execution of the UI script-code snippet is retrieved. For example, browser 108 may retrieve the output value of the previous execution of UI script-code snippet 112 from memory of client device 102. Operation proceeds to step 210.
In step 210, the user interface of the web page is generated based on a retrieved output value of the UI script-code snippet. For example, browser 108 may generate a user interface of web page 110 using an output value of UI script-code snippet 112 where the output value is retrieved by browser 108 from a memory layer of client device 102. Operation of flowchart 200 is finished at step 210.
Referring back to step 206, in instances where an output value of a previous execution of the UI script-code snippet is not found to be stored in the one or more layers of memory, the flow of steps proceeds to step 212. For example, the flow proceeds to step 212 when script-code snippet manager 114 does not find an output value of UI script-code snippet 112 stored in the one or more layer of memory of client device 102.
In step 212, execution of the UI script-code snippet is controlled and an output value of the execution is obtained. In one embodiment, browser 108 may execute (i.e., render) UI script-code snippet 112. In another embodiment, script-code snippet manager 114 may determine that the execution of UI script-code snippet 112 should by handled by server device 104. Browser 108 may transmit UI script-code snippet 112 to server device 104 for execution, and may receive the output value of the execution from server device 104. Operation proceeds to step 214.
In step 214, the user interface of the web page is generated based on an output value obtained from execution of the UI script-code snippet. For example, browser 108 may generate a user interface of web page 110 using an output value obtained from execution of UI script-code snippet 112 performed by browser 108 or performed by server device 104. Operation of flowchart 200 is finished at step 214.
Embodiments of the present disclosure for improving performance in client side browser-based rendering of user interface script-code snippets may be implemented in various ways. For instance,
As shown in
In general, browser 108 is configured to receive UI script-code snippet 112 of web page 110 for generating a user interface of web page 110. UI script-code snippet 112 may be received in response to an event in web page 110 (e.g., a user input received via web page 110 to request a function or an action). Browser 108 is configured to execute (i.e., render) UI script-code snippet 112 to generate output value of UI script-code snippet 326. Browser 108 is configured to generate the user interface of web page 110 (e.g., a region of web page 110) using output value of UI script-code snippet 326. Browser 108 may store output value of UI script-code snippet 326 in in-memory map 320 and/or in-local storage map 322. As described above, browser 108 is configured to receive input for executing UI script-code snippet 112 of web page 110 multiple times during a browser session, or multiple times over multiple browser sessions for generating the user interface in web page 110. In some embodiments, browser 108 may transmit UI script-code snippet 112 to server device 104 for execution, receive output value of UI script-code snippet 326 from server device 104, and proceed to generate the user interface of web page 110 as described above.
In some embodiments, a current session of web page 110, or browser 108, is a client side monitored session. UI script-code snippet 112 may comprise some aspect of web page 110 (e.g., clipboard actions, printing actions, download or upload actions, etc.) that are to be monitored in browser 108 based on browser security policy parameters 116. The execution of UI script-code snippet 112 may translate or transform UI script-code snippet 112 to output value of UI script-code snippet 326, which may include code for monitoring and enforcing browser policies. For example, once UI script-code snippet 112 is executed, output value of UI script-code snippet 326 may be configured to enforce browser security policy parameters 116 that pertain to actions performed in website 110 as a result of UI script-code snippet 112 code (e.g., clipboard policies, print policies, download or upload policies, etc.). However, the present disclosure is not limited to client side monitored sessions, and in some embodiments, UI script-code snippet 112 is unmanaged and is not monitored in client device 102.
In-memory map 320 is configured to store key 324 as an index to output value of UI script-code snippet 326. For example, in-memory map 320 may comprise an array of keys and values (e.g., in-memory map 326=[{KEY:X, VALUE:Y}, {KEY:X, VALUE:Y}, {KEY:X, VALUE:Y}]), where the values of Y comprise executed (i.e., rendered) code snippets. In order to store or retrieve values from in-memory map 320, memory map key generator 304 is configured to process each code snippet (e.g., UI script-code snippet 112) to generate a unique corresponding key (e.g., key 324). In some embodiments, memory map key generator 304 is configured to use a hashing function to generate key 324 (e.g., key 324=hash (UI script-code snippet 112)). After UI script-code snippet 112 has been executed, script-code snippet manager 114 is configured to store output value of UI script-code snippet 326 in in-memory map 320 using key 324 as an index. Also, chain logic engine 302 may utilize key 324 (e.g., generated by memory map key generator 304) to search for output value of UI script-code snippet 326 in in-memory map 320. In some embodiments, browser 108 is configured to clear in-memory map 320 after each browser 108 session or each time web site 110 is exited or loaded.
In some embodiments, the same keys (e.g., key 324) are used for storing (or retrieving) output value of UI script-code snippet 326 to (or from) in-memory map 320 and in-local storage map 322. Alternatively, the two maps may be different and different keys may be generated for each of them. In other words, key 324 may be the same or different than key 328. For example, similar to the method described above for in-memory map 320, in-local storage map 322 is configured to store key 328 as an index to output value of UI script-code snippet 326. In-local storage map 322 may also store usage parameter 330 to indicate how long to retain (i.e., persist) output value of UI script-code snippet 326 in in-local storage map 322. In this regard, in-local storage map 322 (or one or more elements of in-local storage map 322) may be persistent over multiple browser 108 sessions, after exiting and/or reloading web page 110, or after reboot of client device 102. Each time script-code snippet manager 114 stores or retrieves output value of UI script-code snippet 326 in in-local storage map 322, script-code snippet 114 is configured to update usage parameter 330. For example, usage parameter 330 may indicate the last time output value of UI script-code snippet 326 was accessed or how frequently it is accessed. In-local storage map 322 may comprise an array of keys, values, and corresponding usage parameters (e.g., in-local storage map 322=[{KEY:X, VALUE:Y, PARAMETER:Z}, {KEY:X, VALUE:Y, PARAMETER:Z}, {KEY:X, VALUE:Y, PARAMETERZ}]), where values of Y comprise executed code snippets (e.g., output value of UI script-code snippet 326). Usage parameter 330 may correspond to key 328 and output value of UI script-code snippet 326 in the array of in-local storage map 322 (e.g., {KEY:KEY 328, VALUE:OUTPUT VALUE OF UI SCRIPT-CODE SNIPPET 326, PARAMETER:USAGE PARAMETER 330}). In order to store or retrieve values from in-local storage map 322, local storage map key generator 306 is configured to process (e.g., hash) each code snippet (e.g., UI script-code snippet 112) to generate a unique corresponding key (e.g., key 328). For example, local storage map key generator 306 is configured to generate key 328, and script-code snippet manager 114 is configured to store output value of UI script-code snippet 326 using key 328 as an index in in-local storage map 322. Also, chain logic engine 302 may utilize key 328 to search for (or store) output value of UI script-code snippet 326 in in-local storage map 320 to reuse output value of UI script-code snippet 326.
As described above, browser 108 is configured to receive UI script-code snippet 112 of web page 110 for generating a user interface of web page 110, in response to an event in web page 110. Chain logic engine 302 of script-code snippet manager 114 may determine whether UI script-code snippet 112 has been previously executed, or if it needs to be executed for generating the user interface of web page 110. For example, in-memory map 320 may be more accessible than in-local storage map 322. Chain logic engine 302 may be configured to first determine whether output value of UI script-code snippet 326 is stored in in-memory map 320. In this regard, memory map key generator 304 may be configured to process UI script-code snippet 112 (e.g., using a hash function) to generate key 324. Chain logic 302 may be configured to scan indices of in-memory map 320 for key 324 to find output value of UI script-code snippet 326. If key 324 is not found, chain logic 302 may be configured to determine whether output value of UI script-code snippet 326 is stored in in-local storage map 322. In this regard, local storage map key generator 306 may be configured to process UI script-code snippet 112 (e.g., using a hash function) to generate key 326. Chain logic 302 may be configured to scan indices of in-local storage map 322 for key 326 to find output value of UI script-code snippet 326. In some embodiments, chain logic 302 may be configured to use the same key for scanning in-memory map 320 and in-local storage map 322. In instances where key 326 is not found in in-local storage map 322, chain logic 302 may be configured to control execution of (e.g., rendering) of UI script-code snippet 112 during the current session.
In instances where output value of UI script-code snippet 326 is not found in in-memory map 320 or in-local storage map 322, chain logic engine 302 is configured to determine that client rendering engine 308 may execute (i.e., render) UI script-code snippet 112 to generate output value of UI script-code snippet 326. For example, client rendering engine 308 is configured to execute UI script-code snippet 112 to output value of UI script-code snippet 326. Browser 108 is configured to generate the UI of web page 110 based on output value of UI script-code snippet 326. Script-code snippet manager 114 is configured to store output value of UI script-code snippet 326 in in-memory map 320 and/or in-local storage map 322 utilizing memory map key generator 304 and/or local storage map key generator 306 respectively, as described above.
Alternatively, or in addition, in instances where output value of UI script-code snippet 326 is not found in in-memory map 320 or in-local storage map 322, server rendering manager 310 may be configured to determine whether execution of UI script-code snippet 112 should be handled by server device 104 rather than browser 108. For example, rendering-cost logic engine 312 is configured to determine a cost of performing the execution of UI script-code snippet 112 and compare the cost to cost threshold 314. In response to the cost having a predetermined relationship to cost threshold 314, server rendering manager 310 is configured to transmit UI script-code snippet 112 to server device 104 for performing the execution of script-code snippet 112 to generate output value of UI script-code snippet 326. Server rendering manager 310 is configured to receive output value of UI script-code snippet 326 from server device 104 and provide it to browser 108. Browser 108 is configured to generate the user interface of web page 110 based on output value of UI script-code snippet 326 received from server device 104. Script-code snippet manager 114 is configured to store output value of UI script-code snippet 326 received from server device 104 in in-memory map 320 and/or in-local storage map 322 utilizing memory map key generator 304 and/or local storage map key generator 306 as described above
In instances where chain logic engine 302 scans the indices of in-memory map 320 for key 324 to find output value of UI script-code snippet 326, and finds key 324, browser 108 is configured to retrieve output value of UI script-code snippet 326 from in-memory map 320, and generate the user interface of web page 110 in the current session using the retrieved output value of UI script-code snippet 326 from in-memory map 320.
In instances where chain logic engine 302 scans the indices of in-local storage map 322 for key 326 to find output value of UI script-code snippet 326, and finds key 326, browser 108 is configured to retrieve output value of UI script-code snippet 326 from in-local storage map 322, and generate the user interface of web page 110 in the current session using the retrieved output value of UI script-code snippet 326 from in-local storage map 322. Script-code snippet manager 114 may be configured to store the retrieved output value of UI script-code snippet 326 from in-local storage map 322 in in-memory map 320 utilizing memory map key generator 304, as described above.
Generating the user interface of web page 110 based on the retrieved output value of the UI script-code snippet 326 from in-memory map 320 or from in-local storage map 322 is performed faster than generating the user interface based on execution of UI script-code snippet 112 by client rendering engine 308 or by server device 104.
In some embodiments, in response to an initial rendering of web page 110 in a browser session, browser 108 is configured to purge some of the old data from in-local storage map 322 for a user of web page 110 to make storage available for storing additional output values of UI script-code snippets 326 for the user. For example, browser 108 may clean data from in-local storage map 322 based on usage parameters 330. In local-storage 322 may not be completely emptied because it retains some past values that were saved from prior sessions. In general, keys and output values may enter and exit in-local storage map 322 according to the usage of particular users. For example, if a user accesses a certain application or report more often, script-code snippet output values from that report will be retained in in-local storage map 322, and browser 108 may respond faster at generating a user interface of a web page for this report. If a second user accesses another report more often, an in-local storage map for that user will retain script-code snippet output values from the other report, enabling a faster generation of a user interface of the other report for the second user. In this manner each user will have a customized performance improvement according to their usage characteristics.
In embodiments, systems 100 and 300 may operate in various ways to perform their functions. For example,
Flowchart 400 of
In step 404, it may be determined whether an in-memory map indicates a stored output value of the UI script-code snippet generated by prior execution of the UI script-code snippet. For example, chain logic engine 302 may determine whether in-memory map 320 indicates a stored output value of the UI script-code snippet 326 generated by prior execution of UI script code snippet 112. Chain logic 302 may scan in-memory map 320 for output value of UI script-code snippet 326. Operation proceeds to step 406.
In step 406, in instances where in-memory map 320 does not indicate prior output value of UI script-code snippet 326, the processing flow proceeds to step 408. For example, if chain logic engine 302 does not find output value of UI script-code snippet 326 stored in in-memory map 320, the processing flow proceeds to step 408.
In step 408, in response to determining the in-memory map does not indicate the stored output value of the UI script-code snippet, it may be determined whether an in-local storage map for the browser indicates the stored output value of the UI script-code snippet generated by prior execution of the UI script-code snippet. For example, chain logic 302 may determine whether in-local storage map 322 indicates output value of UI script-code snippet 326 generated by prior execution of UI script-code snippet 112. Chain logic 302 may search for output value of UI script-code snippet 326 in in-local storage map 322. Operation proceeds to step 410.
In step 410, in instances when in-local storage map 322 does not indicate prior output value of UI script-code snippet 326, the processing flow proceeds to step 412. For example, if chain logic engine 302 does not find output value of UI script-code snippet 326 stored in in-local storage map 322, the processing flow proceeds to step 412
In step 412, in response to determining the in-local storage map does not indicate the output value of the UI script-code snippet, execution of the UI script-code snippet is controlled in the current session to generate the output value of the UI script-code snippet. A user interface of the web page is generated based on the generated output value of the UI script-code snippet 326. The output value may be stored in the in-memory map and in the in-local storage map. For example, in instances where chain logic engine 302 does not find output value of UI script-code snippet 326 stored in in-local storage map 322, chain logic engine 302 may control rendering engine 308 to execute (i.e., render) UI script-code snippet 112 to generate output value of UI script-code snippet 326. Browser 108 may generate the UI of web page 110 based on output value of UI script-code snippet 326 from rendering engine 308. In some embodiments, script-code snippet manager 114 is configured to store output value of UI script-code snippet 326 generated by rendering engine 308 in in-memory map 320 and/or in-local storage map 322, for example, utilizing memory map key generator 304 and/or local storage map key generator 306 respectively as described above. Operation of flowchart 400 is finished at step 412.
Alternatively, or in addition, in instances where output value of UI script-code snippet 326 is not found in-memory map 320 or in-local storage map 322, server rendering manager 310 may transmit UI script-code snippet 112 to server device 104 for performing the execution of script-code snippet 112 to generate output value of UI script-code snippet 326. Server rendering manager 310 may receive output value of UI script-code snippet 326 from server device 104 and provide it to browser 108. Browser 108 may generate the UI of web page 110 based on output value of UI script-code snippet 326 received from server device 104. Script-code snippet manager 114 may store output value of UI script-code snippet 326 received from server device 104 in in-memory map 320 and/or in-local storage map 322, for example, utilizing memory map key generator 304 and/or local storage map key generator 306 respectively, as described above
In embodiments, systems 100 and 300 may operate in various ways to perform their functions. For example,
Flowchart 500 of
In step 504, in response to determining the in-local storage map does indicate the output value of the UI script-code snippet, returning the output value of the UI script-code snippet from the in-local storage map for use in the current session and storing the output value in the in-memory map. For example, with reference to step 410 of flowchart 400, in instances where chain logic engine 302 finds that in-local storage map 322 does indicate prior output value of UI script-code snippet 326, browser 108 may retrieve output value of UI script-code snippet 326 from in-local storage map 320. Browser 108 may generate the user interface of web page 110 in the current session using output value of UI script-code snippet 326 retrieved from in-local storage map 320. Script-code snippet manager 114 may store output value of UI script-code snippet 326 from in-local storage map 322 to in-memory map 320, for example, utilizing memory map key generator 304, as described above. Operation is finished at step 504.
In embodiments, systems 100 and 300 may operate in various ways to perform their functions. For example,
Flowchart 600 of
In step 604, the cost may be compared to a cost threshold. For example, rendering-cost logic engine 312 may compare the cost of performing the execution of UI script-code snippet 112 to cost threshold 314.
In step 606, the UI script-code snippet may be transmitted to a server for performing the execution of the script-code snippet in response to the cost having a predetermined relationship with a cost threshold. For example, in response to the cost having a predetermined relationship to cost threshold 314, server rendering manager 310 may transmit UI script-code snippet 112 to server device 104. Server device 104 may perform the execution of script-code snippet 112. Server device 104 may execute script-code snippet 112 and generate output value of UI script-code snippet 326.
In step 608, the output value of the script-code snippet may be received from the server device. For example, server rendering manager 310 may receive output value of UI script-code snippet 326 for generation of the user interface of web page 110, as described above.

Alternatively or in addition, chain logic 302 may be configured to determine whether in-local storage map 322 indicates output value of UI script-code snippet 326 generated by prior execution of UI script-code snippet 112. In-local storage map 322 may store key 328 as an index to output value of UI script-code snippet 326. Local storage map key generator 306 may generate key 328 by processing script-code snippet 112 (e.g., using a hash function).
In step 704, the key may be used for said determining whether an in-memory map indicates a stored output value of the UI script-code snippet. For example, chain logic engine 302 may utilize key 324 to scan for output value of UI script-code snippet 326 in in-memory map 320.
In step 706, the key may be used for said determining whether an in-local storage map for the browser indicates the stored output value of the UI script-code snippet. For example, chain logic engine 302 may utilize key 328 to scan for output value of UI script-code snippet 326 in in-local storage map 322.
In some embodiments, in-memory map 320 and in-local storage map 322 may use the same key values as indices for output value of UI script-code snippet 326. In this embodiment, chain logic 302 may use the same key (e.g., key 324 or key 328) for scanning in-memory map 320 and in-local storage map 322 to find (or store) output value of UI script-code snippet 326.

The method comprises: receiving a user interface (UI) script-code snippet from a web page during a current session; and determining whether an in-memory map indicates a stored output value of the UI script-code snippet generated by prior execution of the UI script-code snippet. In response to determining the in-memory map does not indicate the stored output value of the UI script-code snippet, determine whether an in-local storage map for the browser indicates the stored output value of the UI script-code snippet generated by prior execution of the UI script-code snippet. In response to determining the in-local storage map does not indicate the output value of the UI script-code snippet: control execution of the UI script-code snippet for the current session to generate the output value of the UI script-code snippet, generate a user interface of the web page based on the generated output value of the UI script-code snippet; and store the output value in the in-memory map and in the in-local storage map.
In an embodiment of the foregoing computer-readable medium, the computer-readable medium further comprises: in response to determining the in-memory map does indicate the stored output value of the UI script-code snippet, returning the output value of the UI script-code snippet from the in-memory map for use in the current session; or in response to determining the in-local storage map does indicate the output value of the UI script-code snippet, returning the output value of the UI script-code snippet from the in-local storage map for use in the current session and storing the output value in the in-memory map.
In the foregoing computer-readable medium, the computer-readable medium further comprises: retrieving the output value of the UI script-code snippet indicated by the in-memory map or the in-local storage map; and generating a user interface of the web page based on the retrieved output value of the UI script-code snippet. The retrieved output value of the UI script-code snippet comprises a prior executed portion of the web page; and said generating a user interface of the web page based on the retrieved output value of the UI script-code snippet is performed faster than generating the user interface based on said controlling execution of the UI script-code snippet for the current session to generate the output value of the script-code snippet..
