Succesful Status Codes

200	OK	Action complete successfully
201	Created	Success following a POST command
202	Accepted	The request has been accepted for processing, but the processing has not been completed.
203	Partial Information	Response to a GET command, indicates that the returned meta information is from a private overlaid web.
204	No Content	Server has received the request but there is no information to send back.
205	Reset Content	Request fulfilled and user agent should reset document that caused the request. Used to allow user input followed by reseting the input form. The response MUST NOT include an entity.
206	Partial Content	The requested file was partially sent. Usually caused by stopping or refreshing a web page.

Redirection Status Codes

300	Multiple Choices	Requested resource corresponds to a set of representations, each with its own location. Negotiation information is provided so that the representation can be selected and redirect appropriately.
301	Moved Permanently	Requested a directory instead of a file. The web server substituted the index.htm file.
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.
303	See Other	The response to the request is at a different URI and should be retrieved there using a GET method. This allows the output of a POST-activated script to redirect the user agent to a selected resource.
304	Not Modified	The cached version of the requested file is the same as the file to be sent.
305	Use Proxy	The requested resource must be accessed through the proxy given in the Location field. The recipient should repeat this request via the proxy. This response must only be generated by origin servers.
306	Unused	Reserved for future use
307	Temporary redirect	The requested resource resides temporarily under a different URI.

Client Error Status Codes

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	User fail to provide a valid user name / password required for access to file / directory.
402	Payment Required	Reserved for future use
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.
405	Method Not Allowed	The method in the Request-Line is not allowed for the resource identified by the Request-URI. The response must include an Allow header containing a list of valid methods for the requested resource.
406	Not Acceptable	The resource identified by the request is only capable of generating response entities which have content characteristics not acceptable according to the accept headers sent in the request.
407	Proxy Authentication Required	This code is similar to 401 (Unauthorized), but indicates that the client must first authenticate itself with the proxy.
408	Request Time-Out	The client did not produce a request within the time that the server was prepared to wait. The client MAY repeat the request without modifications at any later time.
409	Conflict	The request could not be completed due to a conflict with the current state of the resource.
410	Gone	The requested resource is no longer available at the server and no forwarding address is known.
411	Length Required	The server refuses to accept the request without a defined Content-Length of the message-body. The client may repeat the request if it adds it.
412	Precondition Failed	A condition in the header field data passed by the client evaluated false on the server. This lets the client prevent the requested method from being applied to a resource other than the one intended.
413	Request Entity Too Large	The server refused to process the request because the request entity too large. The server may close the connection to prevent the client from continuing the request.
414	Request-URI Too Large	The server is refusing to service the request because the Request-URI is longer than the server is willing to interpret.
415	Unsupported Media Type	The server is 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.
416	Unsatisfiable Request Range	A server SHOULD return a response with this status code if a request included a Range request-header field
417	Expectation Failed	The server could not meet the expectation in an Expect request-header field. If the server is a proxy, the server has unambiguous evidence that the request could not be met by the next-hop server.

Server Error Status Codes

500	Server Error	The server encountered an unexpected condition which prevented it from fulfilling the request
501	Not Implemented	The server does not support the facility required.
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	Out of Resources	The server cannot process the request due to a system overload. This (should) be a temporary condition.
