1xx Informational
Request received, continuing process.
| |
|
| Code |
Status |
Explanation |
| 100 |
Continue |
This means that the server has received the request headers, and that the client
should proceed to send the request body (in the case of a request for which a body
needs to be sent; for example, a POST request). |
| 101 |
Switching Protocols |
When requesting a page, a browser might receive a status code of 101, followed
by an "Upgrade" header showing that the server is changing to a different version of HTTP. |
| 102 |
Processing (WebDAV) |
This is a HTTP status code shown when WebDAV is processing. |
| 122 |
Request-URI too long |
A Microsoft extension which occurs only in IE7, when the request URI is longer
than 2032 characters, the maximum string length. |
2xx Success
The action was successfully received, understood, and accepted.
| |
|
| Code |
Status |
Explanation |
| 200 |
OK |
Standard response for HTTP successful requests. |
| 201 |
Created |
The request has been fulfilled and resulted in a new resource being created.
When new pages are created by posted form data or by a CGI process, this is confirmation that it worked. |
| 202 |
Accepted |
The client's request was accepted, though not yet processed.
The request might or might not eventually be acted upon, as it might
be disallowed when processing actually takes place. |
| 203 |
Non-Authorative Information |
The information contained in the entity header is not from the original site, but from a third party server. |
| 204 |
No Content |
If you click a link which has no target URL, this response is elicited by the server.
It is silent and does not warn the user about anything. |
| 205 |
Reset Content |
This allows the server to reset any content returned by a CGI. |
| 206 |
Partial Content |
The requested file was not downloaded entirely. This is returned when the user presses
the stop button before a page is loaded, for example, or split a download into multiple simultaneous streams. |
3xx Redirection
The client must take additional action to complete the request.
The action required may be carried out by the user agent without interaction with the user if and
only if the method used in the second request is GET or HEAD.
| |
|
| Code |
Status |
Explanation |
| 300 |
Multiple Choices |
Indicates multiple options for the resource that the client may follow. Example:
The requested address refers to more than one file. Depending on how the server is configured,
you get an error or a choice of which page you want. |
| 301 |
Moved Permanently |
If the server is set up properly it will automatically redirect the reader to
the new location of the file. You should use this redirect when working with SEO. |
| 302 |
Moved Temporarily |
Page has been moved temporarily, and the new URL is available. You should be sent there by the server. |
| 303 |
See Other |
The response to the request can be found under another URI using a GET method.
Data is somewhere else and the GET method is used to retrieve it. When received in response to a PUT, it should be assumed that
the server has received the data and the redirect should be issued with a separate GET message. |
| 304 |
Not Modified |
If the request header includes an 'if modified since' parameter, this code will
be returned if the file has not changed since that date. Search engine robots may generate a lot of these.
Utilizing this saves bandwidth and reprocessing on both the server and client. |
| 305 |
Use Proxy |
The recipient is expected to repeat the request via the proxy. Many HTTP clients (such
as Mozilla and Internet Explorer) do not correctly handle responses with this status code, primarily for
security reasons. |
| 306 |
Switch Proxy |
Not used. |
| 307 |
Temporary Redirect |
In this occasion, the request should be repeated with another URI, but future requests
can still use the original URI. In contrast to http status code 303, the request method should not be changed
when reissuing the original request. For instance, a POST request must be repeated using another POST request. |
4xx Client Error
The client failed to provide an valid request.
| |
|
| Code |
Status |
Explanation |
| 400 |
Bad Request |
There is a syntax error in the request, and it is denied. |
| 401 |
Authorization Required |
The request header did not contain the necessary authentication codes, and the client is denied access. |
| 402 |
Payment Required |
Payment is required. This code is not in operation. |
| 403 |
Forbidden |
The request was a legal request, but the server is refusing to respond to it. This is also returned at times when the server
does not want any more visitors. |
| 404 |
Not Found |
The requested file was not found on the server. Possibly because it was deleted, or never existed before.
Often caused by misspellings of URLs. |
| 405 |
Method Not Allowed |
The method you are using to access the file is not allowed. Examples: using GET on a form which requires
data to be presented via POST, or using PUT on a read-only resource. |
| 406 |
Not Acceptable |
The requested file exists but cannot be used as the client system does not understand the format the file
is configured for. |
| 407 |
Proxy Authentication Required |
The request must be authorised before it can take place. |
| 408 |
Request Timed Out |
The server took longer than its allowed time to process the request. Often caused by heavy internet traffic. |
| 409 |
Conflicting Request |
Too many concurrent requests for a single file. |
| 410 |
Gone |
The file used to be in this position, but is there no longer. This should be used when a resource has been intentionally removed;
however, in practice, a 404 Not Found is often issued instead. Upon receiving a 410 status code, the client should not request the
resource again in the future. Clients such as search engines should remove the resource from their indexes to prevent repeated requests. |
| 411 |
Content Length Required |
The request is missing its Content-Length header. |
| 412 |
Precondition Failed |
A certain configuration is required for this file to be delivered, but the client has not set this up. |
| 413 |
Request Entity Too Long |
The requested file was too big to process. |
| 414 |
Request URI Too Long |
The address you entered was too long for the server. |
| 415 |
Unsupported Media Type |
The filetype of the request is unsupported. |
| 416 |
Requested Range Not Satisfiable |
The client has asked for a portion of the file, but the
server cannot supply that portion (for example, if the client asked for a part of
the file that lies beyond the end of the file). |
| 417 |
Expectation Failed |
You get Expectation Failed as response. |
| 422 |
Unprocessable Entity |
Used with WebDAV. The request was well-formed but was unable to be followed due to semantic errors. |
| 423 |
Locked |
Used with WebDAV. The resource that is being accessed is locked. |
| 424 |
Failed Dependency |
Used with WebDAV. The request failed due to failure of a previous request (e.g. a PROPPATCH). |
| 425 |
Unordered Collection |
Used with WebDAV. Defined in drafts of WebDav Advanced Collections, but not present in "Web Distributed
Authoring and Versioning (WebDAV) Ordered Collections Protocol" |
| 426 |
Upgrade Required |
The client should switch to TLS/1.0. |
| 449 |
Retry With |
A Microsoft extension. The request should be retried after doing the appropriate action. |
| 450 |
Blocked |
A Microsoft extension. Used for blocking sites with Windows Parental Controls. |
