Abstract

An identification of one of multiple types of Web browsers that a Web page supports, as well as an identification of one of multiple versions of that one type of Web browser that the Web page supports, is obtained. The Web page is displayed using the identified version of the identified Web browser type. A request for an identification of the identified version of the identified Web browser type can also be received from a program, such as a Web page script. In response to the request, an identification of the identified version of the identified Web browser type is being used to display the Web page is returned, and instructions of the program are executed based at least in part on the identified version of the identified Web browser type.

Claims

1. One or more computer storage media having stored thereon multiple instructions that, when executed by one or more processors of a device, cause the one or more processors to:

access a Web page;

obtain an identification of one type of multiple types of Web browsers that the Web page supports;

obtain, for the identified one type of Web browser, an identification of one version of multiple versions of the identified one type of Web browser that the Web page supports; and

present the Web page using the identified one version of the identified one type of Web browser.

2. One or more computer storage media as recited in claim 1, the multiple instructions comprising a Web browser.

3. One or more computer storage media as recited in claim 1, wherein to obtain the identification of the one type and the identification of the one version is to obtain the identification of the one type and the identification of the one version from the Web page.

4. One or more computer storage media as recited in claim 1, wherein to obtain the identification of the one type of multiple types of Web browsers and to obtain the identification of the one version is to:

obtain identifications of multiple types of Web browsers and corresponding Web browser versions that the Web page supports;

select, from all versions of all Web browser types that the Web page supports, one version of one Web browser type; and

use the selected one version of one Web browser type as the identified one version of the identified one type of Web browser.

5. One or more computer storage media as recited in claim 1, the identification of the one version comprising an identification that a most recent version of the identified type of Web browser that is available on the device is the one version.

6. One or more computer storage media as recited in claim 1, the instructions further causing the one or more processors to generate a compatible collection object having multiple elements, each of the multiple elements identifying a particular type of Web browser and a corresponding particular version of the Web browser that the Web page supports.

7. One or more computer storage media as recited in claim 1, the instructions further causing the one or more processors to:

receive, from a script included in the Web page, a request for an identification of the identified one type of Web browser and the identified one version; and

return, to the script, the identification of the identified one type of Web browser and the identified one version.

8. One or more computer storage media as recited in claim 7, wherein to return the identification is to return both a Web browser type identifier of the one type of Web browser and a version identifier of the identified one version.

9. One or more computer storage media as recited in claim 7, wherein to return the identification is to return a true indication if a Web browser type and corresponding version identified in the request is the identified one type of Web browser and the identified one version, and otherwise to return a false indication.

10. One or more computer storage media as recited in claim 1, the instructions further causing the one or more processors to, after the identification of the one type and identification of the one version are obtained, begin execution of the identified one version of the identified one type of Web browser.

11. A method comprising:

identifying which of multiple Web browser versions a Web page supports, the multiple Web browser versions being multiple versions of multiple types of Web browsers;

selecting, based at least in part on which of the multiple Web browser versions the Web page supports, a version of a Web browser type; and

displaying the Web page using the selected version of the Web browser type.

12. A method as recited in claim 11, the identifying comprising accessing one or more meta tags included in the Web page, each meta tag including an identifier of a Web browser type and corresponding version that the Web page supports.

13. A method as recited in claim 11, the selecting comprising selecting a most recent version of a Web browser type that is both identified in the Web page and that is included as a version of the Web browser on a device implementing the method.

14. A method as recited in claim 11, further comprising:

receiving, from a program included in the Web page, a request for an identification of the selected version of the Web browser type; and

returning, to the program, the identification of the selected version of the Web browser type.

15. A method as recited in claim 14, the program comprising a Web page script obtained from a different server than a server from which the Web page is obtained.

16. One or more computer storage media having stored thereon a program that, when executed by one or more processors of a device, causes the one or more processors to:

request an identification of a Web browser type and corresponding version that has been selected to display a Web page;

receive, in response to the request, the identification of the Web browser type and corresponding version that has been selected to display the Web page; and

execute one or more instructions of the program based at least in part on the Web browser type and corresponding version that has been selected to display the Web page.

17. One or more computer storage media as recited in claim 16, wherein to receive the identification is to receive both a Web browser type identifier of the Web browser type that has been selected to display the Web page, and a version identifier of the version of the Web browser type that has been selected to display the Web page.

18. One or more computer storage media as recited in claim 16, wherein to request the identification is to invoke a method that identifies a particular Web browser type and a particular corresponding version, and wherein to receive the identification is to receive a true or false indication of whether the particular Web browser type and the particular corresponding version has been selected to display the Web page.

19. One or more computer storage media as recited in claim 16, the program comprising a Web page script.

20. One or more computer storage media as recited in claim 16, wherein to execute one or more instructions of the program is to select a version of the program to be executed based at least in part on the Web browser type and corresponding version that has been selected to display the Web page.
