Server Error 661

The server refuses to accept the request without a defined content length on the precondition given in one or more of the request header fields evaluated to false when it was tested on the server and refusing to process a request because the request entity is larger than the server is willing or able to process or refusing to service the request because the request URI is longer than the server is willing to interpret, as well as refusing to service the request because the entity of the request is in a format not supported by the requested resource for the requested method, causing the server to encounter an unexpected condition that prevented it from fulfilling the request since the server does not support the functionality required to fulfill the request while acting as a gateway or proxy receiving an invalid response from the upstream server it accessed in attempting to fulfill the request which temporarily overloaded and timed out the server waiting for a gateway that the server does not support, or refuses to support, the HTTP protocol version that was used in the request message.
