Error "Method Not Implemented" - Firefox 3

Getting sporadic errors from CMS users; Sometimes Ajax requests result in the answer “501 Method not implemented” from the server. Not always; usually works.

The application is stable for several months. It seems that users will get it with Firefox 3. I saw a couple of links through Google on such problems related to the presence of "charset = UTF-8" in the Content-type header, but they can be false

Has anyone seen this error or any ideas on what could be causing?

thanks

You can check the server logs to see what causes the problem. For example, it may happen that these requests are garbled, say, due to a lack of implementation of persistent HTTP 1.1 connections.

try it

  • Try clearing cookies and cache
  • Enter approximately: config in the URL bar, a list of configuration settings for Firefox
  • Find the parameter "network.automatic-ntlm-auth.trusted-uris"
  • Set the server name value to use NTLM with.
  • Find the parameter "network.negotiate-auth.trusted-uris"
  • Set the server name value to use NTLM with.
  • network.automatic-ntlm-auth.allow-proxies = True
  • Firefox Reboot - Test Application URL

The problem occurs because your application does not work in the same domain as your service. You need to configure the server to accept these calls by adding the header "Access-Control-Allow-Origin".
