CODES and what they all mean Error
codes 500 - 505
Internal Error 500
The server encountered an unexpected condition which prevented it from fulfilling the
request. Your request could not be processed due to an internal server error.
Not implemented 501
The server does not support the functionality required to fulfill the request. This is the
appropriate response when the server does not recognize the request method and is not
capable of supporting it for any resource.
502 Bad Gateway
The server, while acting as a gateway or proxy, received an invalid response from the
upstream server it accessed in attempting to fulfill the request.
503 Service Unavailable
The server is currently unable to handle the request due to a temporary overloading or
maintenance of the server. The implication is that this is a temporary condition which
will be alleviated after some delay. If known, the length of the delay may be indicated in
a Retry-After header. If no Retry-After is given, you should handle the response as it
would for a 500 response.
504 Gateway Timeout
The server, while acting as a gateway or proxy, did not receive a timely response from the
upstream server it accessed in attempting to complete the request.
505 HTTP Version Not Supported
The server does not support, or refuses to support, the HTTP protocol version that was
used in the request message. The response should contain an entity describing why that
version is not supported and what other protocols are supported by that server.
