200 Error
OK – The request has succeeded. The information returned with the response is dependent on the method used in the request.
Category : Errors
301 Redirect
Moved Permanently – The requested resource has been assigned a new permanent URI and any future references to this resource SHOULD use one of the returned URLs.
302 Redirect
Found – The requested resource resides temporarily under a different URI. Since the redirection might be altered on occasion, the client SHOULD continue to use the Request-URI for future requests.
304 Error
Not Modified – If the client has performed a conditional GET request and access is allowed, but the document has not been modified, the server SHOULD respond with this status code.
307 Error
Temporary Redirect – The requested resource resides temporarily under a different URI. Since the redirection MAY be altered on occasion, the client SHOULD continue to use the Request-URI for future requests.
400 Error
Bad Request – The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications.
401 Redirect
Unauthorized – The request requires user authentication. The response MUST include a WWW-Authenticate header field containing a challenge applicable to the requested resource.
403 Error
Forbidden – The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated. The underlying idea is that the page or resource you are trying to reach is absolutely not accessible for some reason.
404 Error
404 Not Found Error – The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
410 Error
Gone – The requested resource is no longer available at the server and no forwarding address is known. This condition is expected to be considered permanent. This error is similar to 404 – Not Found, but a 410 error suggests that the page may still exist in another location. The URL however, is effectively useless without forwarding [...]
500 Error
Internal Server Error – The server encountered an unexpected condition which prevented it from fulfilling the request.
501 Error
Not Implemented – 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.
