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 at least one runtime capability check, comprising:

determining whether first result information stored in response to performing a first runtime capability check is available or is not available, wherein the first runtime capability check includes testing one or more first functions of a client application;

in response to determining that the first result information is not available, performing the first runtime capability check;

storing the first result information in response to performing the first runtime capability check, wherein the first result information indicates the client application does not support at least one function of the one or more first functions;

sending the first result information to a server computing device;

receiving limited-feature rendered content from the server computing device;

performing a second runtime capability check, wherein the second runtime capability check includes testing one or more second functions of the client application;

storing second result information in response to performing the second runtime capability check, wherein the second result information indicates the client application supports the one or more second functions;

sending the second result information to the server computing device; and

receiving full-feature rendered content from the server computing device.

2. The method of claim 1, wherein the client application is a browser application and wherein the one or more first functions are different from the one or more second functions.

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 first runtime capability check comprises obtaining test code for the one or more first functions, setting a result value based on an execution of the test code for the one or more first 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 first result information based on the performance of the first runtime capability check comprises storing the first 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 first 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 whether the first result information stored in response to performing the first runtime capability check is available or not available comprises determining when a cookie that stores the first result information exists.

9. The method of claim 4, further comprising determining when at least one of the tested first functions fails before the test code finishes executing.

10. A hardware computer storage device, having computer-executable instructions that, when executed by a processor, perform a method for adaptive rendering based on at least one runtime capability check, the method comprising:

determining whether first result information stored in response to performing a first runtime capability check is available or is not available, wherein the first runtime capability check includes testing one or more first functions of a client application;

in response to determining that the first result information is not available, performing the first runtime capability check on a computing device using a browser application;

storing the first result information in response to performing the first runtime capability check, wherein the first result information indicates the client application does not support at least one function of the one or more first functions;

sending the first result information to a server computing device;

receiving limited-feature rendered content from the server computing device;

performing a second runtime capability check, wherein the second runtime capability check includes testing one or more second functions of the client application;

storing second result information in response to performing the second runtime capability check, wherein the second result information indicates the client application supports the one or more second functions;

sending the second result information to the server computing device; and

receiving full-feature rendered content from the server computing device.

11. The hardware computer storage device of claim 10, the method further comprising determining if the browser supports a client side scripting language.

12. The hardware computer storage device of claim 10, wherein performing the first runtime capability check comprises setting a result value based on an execution of test code for the one or more first functions, and storing the result value for use when subsequently rendering content.

13. The hardware computer storage device 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 hardware computer storage device of claim 10, wherein storing the first result information in response to the performance of the first runtime capability check comprises storing the first result information in a cookie that is used by the server computing device to adaptively generate content that is rendered using the browser.

15. The hardware computer storage device of claim 10, the method further comprising providing the first 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.

16. The hardware computer storage device of claim 10, wherein determining whether first result information stored in response to performing a first runtime capability check is available comprises determining when a cookie that stores the first 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 perform actions comprising;

determining if a browser supports a client side scripting language;

determining whether first result information stored in response to preforming a first runtime capability check is available or is not available, wherein the first runtime capability check includes testing one or more first functions of a client application;

in response to determining that the first result information is not available, performing the first runtime capability check on a computing device using the browser application;

storing the first result information in response to performing the first runtime capability check, wherein the first result information indicates the client application does not support at least one function of the one or more first functions;

sending the first result information to a server computing device;

receiving limited-feature rendered content from the server computing device;

performing a second runtime capability check, wherein the second runtime capability check includes testing one or more second functions of the client application;
