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 runtime capability checks of a client application on a computing device, comprising:

determining whether first result information stored in response to performing a first runtime capability check of the client application is available, wherein the first runtime capability check includes testing a plurality of first functions of the client application;

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

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

sending the first result information to the computing device;

in response to first result information, adapting rendering code for at least one of the first functions not supported by client application;

in response to first result information, generating code for supported first functions;

performing a second runtime capability check of the client application;

storing second result information in response to performing the second runtime capability check of the client application;

wherein the second result information indicates the client application does not support at least one function of second functions;

sending the second result information to the computing device;

in response to second result information, adapting rendering code for at least one of the second functions not supported by client application;

in response to second result information, generating code for supported second functions;

and

delivering limited-feature rendered content to the client application based on the adapted and generated code.

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 application supports a client side scripting language that is received from the 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 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 comprises storing the first result information in a cookie that is passed to the computing device and is used by the computing device to adaptively generate content that is rendered on the client application.

7. The method of claim 1, further comprising providing the first result information to the 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 comprises determining whether a cookie that stores the first result information exists.

9. The method of claim 1, wherein determining whether the first result information stored in response to performing the first runtime capability check is available comprises determining whether a valid cookie that stores the first result information exists.

10. The method of claim 4, further comprising determining that at least one of the tested first functions crashed, and maintaining a failed value for each of the tested first functions that crashed.

11. 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 of a client application on a computing device, the method comprising:

determining whether first result information stored in response to performing a first runtime capability check of the client application is available, wherein the first runtime capability check includes testing a plurality of first functions of the client application;

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

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

sending the first result information to the computing device;

in response to first result information, adapting rendering code for at least one of the first functions not supported by client application;

in response to first result information, generating code for supported first functions;

performing a second runtime capability check of a client application;

storing a second result information in response to performing the second runtime capability check of the client application;

wherein the second result information indicates the client application does not support at least one function of second functions;

sending the second result information to the computing device;

in response to second result information, adapting rendering code for at least one of the second functions not supported by client application;

in response to second result information, generating code for supported second functions;

and

delivering limited-feature rendered content to client application.

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

13. The hardware computer storage device of claim 11, 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.

14. The hardware computer storage device of claim 13, 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.

15. The hardware computer storage device of claim 11, wherein determining whether the first result information stored in response to performing the first runtime capability check is available or not available comprises determining whether a non-expired cookie that stores the first result information exists.

16. The hardware computer storage device of claim 14, further comprising determining that at least one of the tested first functions crashed, and maintaining a start value for each of the tested first functions that crashed.

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;
