"Method Not Implemented" error - Firefox 3

Question

Hi all

Getting sporadic errors from users of a CMS; Ajax requests sometimes result in a "501 Method not implemented" response from the server. Not all the time; usually works.

Application has been stable for months. Users seem to be getting it with Firefox 3. I've seen a couple references via Google to such problems being related to having "charset=UTF-8" in the Content-type header, but these may be spurious

Has anyone seen this error or have any ideas about what the cause could be?

Thanks

Ian

Answer 1

You may want to check the logs of the server to see what's causing the issue. For example, it might be that these requests are garbled, say, because of a flaw in the HTTP 1.1 persistent connection implementation.

Answer 2

Try this

1. Try clearing your cookies and your cache
2. Type about:config into the URL bar, list of configuration settings for Firefox
3. Locate the setting for 'network.automatic-ntlm-auth.trusted-uris'
4. Set the value of names of the servers to use NTLM with.
5. Locate the setting for 'network.negotiate-auth.trusted-uris'
6. Set the value of names of the servers to use NTLM with.
7. network.automatic-ntlm-auth.allow-proxies = True
8. Restart Firefox - Test URL to application
