Abstract

The present invention extends to methods, systems, and computer program products for identifying appropriate client-side script references. Embodiments of the invention facilitate tailoring a list of script references to send to a Web browser based on a list of script references included in a server page. Referenced scripts sent to a Web browser can differ from referenced scripts included in the server page. Script references sent to a Web browser can refer to scripts optimized for the execution environment of the Web browser and to scripts stored at preferred script sources. Further, duplicate script references are removed prior to sending a list of script references to the Web browser. Since script lists sent to Web browsers are tailored for execution environment and duplicates are removed, scripts can be loaded and processed more effectively at Web browsers.

Claims

1. At a Web server, a method for identifying appropriate client-side script references, the method comprising:

an act of receiving a Web page request from the Web browser;

an act of accessing a server side page that corresponds to the Web page;

an act of executing the server side page, including executing a script manager that is included in the server side page;

an act of the script manager receiving a registration request from one or more other controls in the server side page during execution of the server side page, each registration request requesting registration of referenced scripts that are to be used at the Web browser to render the Web page;

for each received registration request, an act of the script manager processing the registration of each referenced script, including;

an act of determining if the referenced script is appropriately optimized for executing in a designated script execution environment at the Web browser;

an act of determining if the referenced script is stored in a location that is an appropriate script source;

an act of determining a new script reference for the referenced script based on the determinations, the new script reference indicating where the Web browser is to obtain an appropriate instance of the script;

an act of determining if the new script reference is already included in the list of script references as a result of processing a prior script reference registration request; and

an act of including the new script reference in the list of script references when the new script reference is not already included in the list of script references; and

an act of rendering the list of script references to the Web browser in response to the Web page request.

2. The method as recited in claim 1, wherein the act of receiving a Web page request from the Web browser comprises an act of receiving a HyperText Transfer Protocol GET message.

3. The method as recited in claim 1, wherein the act of accessing a server side page that corresponds to the Web page comprises an act of accessing an ASP .NET page.

4. The method as recited in claim 1, wherein the act of determining if the referenced script is appropriately optimized for executing in a designated script execution environment at the Web browser comprising an act of determining if the referenced script is a release mode version script or a debug mode version script.

5. The method as recited in claim 1, wherein the act of determining if the referenced script is appropriately optimized for executing in a designated script execution environment at the Web browser comprising an act of determining the geographically location were the Web browser is located.

6. The method as recited in claim 1, wherein the act of determining if the referenced script is appropriately optimized for executing in a designated script execution environment at the Web browser comprising an act of determining if the referenced script is appropriately localized for executing in the execution environment of the Web browser.

7. The method as recited in claim 1, wherein the act of determining if the referenced script is stored in a location that is an appropriate script source comprises an act of determining if the script source for the references script is a disk-based source or an assembly-based source.

8. The method as recited in claim 1, further comprising:

an act of enumerating other instances of the referenced script prior to determining a new script reference for the referenced script.

9. The method as recite in claim 1, wherein the act of determining a new script reference for the referenced script comprises an act of determining a new script reference that refers to a debug a version of the referenced script, wherein the referenced script is a release version script.

10. The method as recite in claim 1, wherein the act of determining a new script reference for the referenced script comprises an act of determining a new script reference that refers to an instance of the referenced script that was selected based on geography

11. The method as recite in claim 1, wherein the act of determining a new script reference for the referenced script comprises an act of determining a new script reference that refers to an appropriately localized version of the script for execution at the Web browser, wherein the referenced script was not appropriately localized for execution at the Web browser.

12. The method as recite in claim 1, wherein the act of determining a new script reference for the referenced script comprises an act of determining a new script reference that refers to an instance of the referenced script stored at a different script source.

13. The method as recite in claim 12, wherein the act of determining a new script reference that refers to an instance of the referenced script stored at a different script source comprises an act of determining a new script reference to a disk-based instance of the referenced script, wherein the referenced script is referenced at an assembly-based script source.

14. The method as recited in claim 1, wherein the act of determining if the new script reference is already included in the list of script referenced comprises:

an act of determining that the new script reference is already included in the list of script references; and

an act of discarding the new script reference.

15. The method as recite in claim 1, wherein the an act of rendering the list of script references to the Web browser comprises an act of sending an HTTP message that includes content and the list of script references to the Web browser.

16. A computer program product for use at a Web server, the computer program product for implementing a method for identifying appropriate client-side script references, the computer-program product comprising one or more computer-readable media having stored thereon computer-executable instructions that, when executed at a processor, cause the Web server to perform the method, including the following:

receive a Web page request from the Web browser;

access a server side page that corresponds to the Web page;

execute the server side page, including executing a script manager that is included in the server side page;

receive a registration request from one or more controls in the server side page during execution of the server side page, each registration request requesting registration of referenced scripts that are to be used at the Web browser to render the Web page;

for each received registration request, process the registration of each referenced script, including the following;

determine if the referenced script is appropriately optimized for executing in a designated script execution environment at the Web browser;

determine if the referenced script is stored in a location that is an appropriate script source;

determine a new script reference for the referenced script based on the determinations, the new script reference indicating where the Web browser is to obtain an appropriate instance of the script;

determine if the new script reference is already included in the list of script references as a result of processing a prior script reference registration request; and

include the new script reference in the list of script references when the new script reference is not already included in the list of script references; and

render the list of script references to the Web browser in response to the Web page request.

17. The computer program product as recited in claim 16, further comprising computer-executable instructions that, when executed, cause the Web server to perform the following:

enumerate other instances of the referenced script prior to determining a new script reference for the referenced script; and

wherein computer-executable instructions that, when executed, cause the Web server to determine a new script reference for the referenced script comprise computer-executable instructions that, when executed, cause the Web server to select a new script reference referring to one of the enumerated other instances of the script.

18. The computer program product as recited in claim 16, wherein computer-executable instructions that, when executed, cause the Web server to determine if the new script reference is already included in the list of script referenced comprise computer-executable instructions that, when executed, cause the Web server to:

determine that the new script reference is already included in the list of script references; and

discard the new script reference.

19. The computer program product as recited in claim 16, wherein computer-executable instructions that, when executed, cause the Web server to render the list of script references to the Web browser comprise computer-executable instructions that, when executed, cause the Web server to sending an HTTP message that includes content and the list of script references to the Web browser.
