SEO Glossary: 0-9



200
OK - The request has succeeded. The information returned with the response is dependent on the method used in the request.
301
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 URIs.
302
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
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
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
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
Unauthorized - The request requires user authentication. The response MUST include a WWW-Authenticate header field containing a challenge applicable to the requested resource.
403
Forbidden - The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated.
404
Not Found - The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
410
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.
500
Internal Server Error - The server encountered an unexpected condition which prevented it from fulfilling the request.
501
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.
