The server failed to fulfill a request.

Response status codes beginning with the digit "5" indicate cases in which the server is aware that it has encountered an error or is otherwise incapable of performing the request. Except when responding to a HEAD request, the server "should" include an entity containing an explanation of the error situation, and indicate whether it is a temporary or permanent condition. Likewise, user agents "should" display any included entity to the user. These response codes are applicable to any request method.
