Abstract

Techniques for clients and servers to use the web authoring extensions, and in particular, extended error handling to allow servers to provider richer web authoring error information to clients. One technique includes sending an authoring request to a server, receiving a response message with extended error information by a client, and sending the extended error information to an application program. Other embodiments are described and claimed.

Claims

1. An article comprising a computer-readable storage medium containing instructions that if executed enable a system to:

send an authoring request to a server;

receive a response message with extended error information by a client; and

send said extended error information to an application program.

2. The article of claim 1, further comprising instructions that if executed enable the system to:

determine said extended error information does not have a file handle; and

store said extended error information in an extended error look up table with a process identifier, thread identifier and login identifier.

3. The article of claim 1, further comprising instructions that if executed enable the system to retrieve said extended error information from an extended error look up table if said extended error information has a file handle.

4. The article of claim 1, further comprising instructions that if executed enable the system to:

determine said extended error information does have a file handle; and

store said extended error information with a file object corresponding to said file handle.

5. The article of claim 1, further comprising instructions that if executed enable the system to retrieve said extended error information from a file object if said extended error information has a file handle.

6. The article of claim 1, further comprising instructions that if executed enable the system to receive said response message with said extended error information having an extended error header name and an accompanying header field comprising information identifying and/or describing a corresponding error.

7. The article of claim 1, further comprising instructions that if executed enable the system to receive said response message with said extended error information having a system error code of said server and a string specifically describing the error.

8. An article comprising a computer-readable storage medium containing instructions that if executed enable a system to:

receive a response message with extended error information from a server;

store said extended error information by a client;

receive a request for said extended error information;

retrieve said extended error information by said client; and

send said extended error information to an application program.

9. The article of claim 8, further comprising instructions that if executed enable the system to store said extended error information in an extended error look up table with a process identifier, thread identifier and login identifier if said extended error information does not have a file handle.

10. The article of claim 8, further comprising instructions that if executed enable the system to retrieve said extended error information from an extended error look up table if said extended error information has a file handle.

11. The article of claim 8, further comprising instructions that if executed enable the system to store said extended error information with a file object corresponding to a file handle.

12. The article of claim 8, further comprising instructions that if executed enable the system to retrieve said extended error information from a file object if said extended error information has a file handle.

13. The article of claim 8, further comprising instructions that if executed enable the system to receive said extended error information with an indication of a server-side error.

14. The article of claim 8, further comprising instructions that if executed enable the system to receive said extended error information from a field body of said response message, said extended error information comprising an operating system error code or a string describing an operating system error.

15. The article of claim 8, further comprising instructions that if executed enable the system to:

parse the response message for an extended error header; and

extract from said extended error header said extended error information having information about an error on the server.

16. An article comprising a computer-readable storage medium containing instructions that if executed enable a system to:

send an authoring request to a client redirector;

receive error information from said client redirector; and

receive extended error information from said client redirector.

17. The article of claim 16, further comprising instructions that if executed enable the system to send a request for said extended error information to said client redirector.

18. The article of claim 16, further comprising instructions that if executed enable the system to:

retrieve a string from said extended error information; and

display said string.

19. The article of claim 16, further comprising instructions that if executed enable the system to:

retrieve an extended error code from said extended error information;

send a request to an operating system for a string associated with said extended error code; and

display said string.

20. The article of claim 16, further comprising instructions that if executed enable the system to receive said extended error information with an indication of a server-side error.
