Abstract

A World Wide Web (web) server built-in service access function (SAF) is overridden with a service having intelligence about the type of user-agent to which an error page is being served. In this way, error messages are served to a client in a platform appropriate manner.

Claims

1. A method for a World Wide Web (Web) server to process an error encountered by a client, said method comprising:

determining an appropriate error file to send to said client, said error file associated with said error;

using a replaced SAF, said replaced SAF;

determining type of client;

adjusting said error file by incorporating said client type; and

sending said adjusted error file to said client.

2. The method of claim 1, said determining type of client, further comprising:

requesting and reading corresponding headers.

3. The method of claim 1, said determining type of client, further comprising:

determining device and running software of said client; and

determining content type of said client.

4. The method of claim 3, further comprising:

said adjusting error file replacing a default error file extension with an appropriate error file extension, said appropriate file extension corresponding to said running software of said client; and

said sending said adjusted error file with said determined content type.

5. The method of claim 1, wherein said client is any of, but not limited to:

a personal computer, a cell phone, a personal digital assistant (PDA), and the like.

6. The method of claim 3, wherein said content type is any of, but not limited to:

Html, wml, and hdml.

7. An apparatus for a World Wide Web (Web) server to process an error encountered by a client, said apparatus comprising:

means for determining an appropriate error file to send to said client, said error file associated with said error;

means for using a replaced SAF, said replaced SAF providing;

means for determining type of client;

means for adjusting said error file by incorporating said client type; and

means for sending said adjusted error file to said client.

8. The apparatus of claim 7, said means for determining type of client, further comprising:

means for requesting and reading corresponding headers.

9. The apparatus of claim 7, said means for determining type of client, further comprising:

means for determining device and running software of said client; and

means for determining content type of said client.

10. The apparatus of claim 9, further comprising:

said means for adjusting error file providing means for replacing a default error file extension with an appropriate error file extension, said appropriate file extension corresponding to said running software of said client; and

said means for sending said adjusted error file with said determined content type.

11. The apparatus of claim 7, wherein said client is any of, but not limited to:

a personal computer, a cell phone, a personal digital assistant (PDA), and the like.

12. The apparatus of claim 7, wherein said content type is any of, but not limited to:

HTML, wml, and hdml.
