Abstract

A runtime capability check determines functionality supported by a client application (e.g. a browser) on a computing device. During the runtime capability check, the client application (e.g. the browser) attempts to execute different function tests to determine its capabilities. The result information from the function tests are stored. The stored result information is used by the client application during subsequent connections with the server (e.g. the cookie is passed from the mobile computing device to the server). Based on the supported functionality as determined by the stored result information, the rendering code is adapted for, generated and delivered to the computing device by the server. For example, when the client application supports the tested functionality then the server renders the content using full feature rendering. When the client application does not support all of the tested functionality then the server renders the content using limited feature rendering.

Claims

1. A method for adaptive rendering based on a runtime capability check, comprising:

determining if result information is available that is based on a run-time capability check that tests functions of a client application that uses content received from a server computing device over a network;

performing the runtime capability check when the result information is not available;

storing the result information based on performing the run-time capability check when the result information is not available; and

using the result information to determine how to render the content.

2. The method of claim 1, wherein the client application is a browser application.

3. The method of claim 2, further comprising determining if the browser supports a client side scripting language that is received from the server computing device.

4. The method of claim 2, wherein performing the runtime capability check comprises obtaining test code for the functions, setting a result value based on an execution of the test code for the functions, and storing the result value for use when subsequently rendering content.

5. The method of claim 4, wherein setting the result value comprises setting the result value to a start value before the test code is executed and changing the result value from the start value to a different result value after the test code is executed.

6. The method of claim 1, wherein storing the result information based on the performance of the runtime capability check comprises storing the result information in a cookie that is passed to the server computing device and is used by the server computing device to adaptively generate content that is rendered using the client application.

7. The method of claim 1, further comprising providing the result information to the server computing device using at least one of:

a cookie, a query string, a postback, a form submit and a web service.

8. The method of claim 1, wherein determining if the result information based on a run-time capability check that tests functions of the application that accesses content over a network is available comprises determining when a cookie that stores the result information exists.

9. The method of claim 1, further comprising determining when at least one of the tested functions fails before the test code finishes executing.

10. A computer-readable medium having computer-executable instructions for adaptive rendering based on a runtime capability check, comprising:

determining if result information is available that is based on a run-time capability check that tests functions of a browser application;

performing the runtime capability check on a computing device using the browser application when the result information is not available;

storing the result information based on performing the run-time capability check when the result information is not available; and

using the result information to render the content using the functions that are supported by the browser.

11. The computer-readable medium of claim 10, further comprising determining if the browser supports a client side scripting language.

12. The computer-readable medium of claim 10, wherein performing the runtime capability check comprises setting a result value based on an execution of the test code for the functions, and storing the result value for use when subsequently rendering content.

13. The computer-readable medium of claim 12, wherein setting the result value comprises setting the result value to a start value before the test code is executed and changing the result value from the start value to a different result value after the test code is executed.

14. The computer-readable medium of claim 10, wherein storing the result information based on the performance of the runtime capability check comprises storing the result information in a cookie that is used by a server computing device to adaptively generate content that is rendered using the browser.

15. The computer-readable medium of claim 10, further comprising providing the result information to a server computing device using at least one of:

a cookie, a query string, a postback, a form submit and a web service.

16. The computer-readable medium of claim 10, wherein determining if the result information based on a run-time capability check that tests functions of the browser comprises determining when a cookie that stores the result information exists.

17. A system for adaptive rendering based on a runtime capability check, comprising:

a processor and a computer-readable medium;

an operating environment stored on the computer-readable medium and executing on the processor; and

a manager operating under the control of the operating environment and operative to actions comprising;

determining if a browser supports a client side scripting language;

determining if result information is available that is based on a run-time capability check that tests functions of the browser application;

performing the runtime capability check on a computing device using the browser application when the result information is not available;

storing the result information based on performing the run-time capability check when the result information is not available; and

using the result information to render the content using the functions that are supported by the browser.

18. The system of claim 17, wherein performing the runtime capability check comprises setting a result value based on an execution of the test code for the functions, and storing the result value for use when subsequently rendering content.

19. The system of claim 18, wherein setting the result value comprises setting the result value to a start value before the test code is executed and changing the result value from the start value to a different result value after the test code is executed.

20. The system of claim 17, further comprising providing the result information to a server computing device using at least one of:

a cookie, a query string, a postback, a form submit and a web service.
