# Getting started HTTP Status Code


What is HTTP Status Code ?

An HTTP status code is a server response to a browsers request. When you visit a website, your browser sends a request to the sites server, and the server then responds to the browsers request with a three-digit code: the HTTP status code.

Means

1xx: Informational It means the request has been received and the process is continuing.
2xx: Success It means the action was successfully received, understood, and accepted.
3xx: Redirection It means further action must be taken in order to complete the request.
4xx: Client Error It means the request contains incorrect syntax or cannot be fulfilled.
5xx: Server Error It means the server failed to fulfill an apparently valid request.

1xx Information

100: Continue Only a part of the request has been received by the server, but as long as it has not been rejected, the client should continue with the request.
101: Switching Protocols The server switches protocol.
102: Processing An interim response used to inform the client that the server has accepted the complete request, but has not yet completed it.

2xx Successful

200: OK The request is OK.
201: Created The request is complete, and a new resource is created .
202: Accepted The request is accepted for processing, but the processing is not complete.
203: Non-Authoritative Information The information in the entity header is from a local or third-party copy, not from the original server.
204: No Content A status code and a header are given in the response, but there is no entity-body in the reply.
205: Reset Content The browser should clear the form used for this transaction for additional input.
206: Partial Content The server is returning partial data of the size requested. Used in response to a request specifying a Range header. The server must specify the range included in the response with the Content-Range header.

3xx Redirection

300: Multiple Choices A link list. The user can select a link and go to that location. Maximum five addresses  .
301: Moved Permanently The requested page has moved to a new url .
302: Found The requested page has moved temporarily to a new url .
303: See Other The requested page can be found under a different url.
304: Not Modified This is the response code to an If-Modified-Since or If-None-Match header, where the URL has not been modified since the specified date.
305: Use Proxy The requested URL must be accessed through the proxy mentioned in the Location header.
306: Unused This code was used in a previous version. It is no longer used, but the code is reserved.
307: Temporary Redirect The requested page has moved temporarily to a new url.

409: Conflict The request could not be completed because of a conflict.

413: Payload Too Large The server will not accept the request, because the request entity is too large.
414: URI Too Long The server will not accept the request, because the URI Too Long response status code indicates that the URI requested by the client is longer than the server is willing to interpret.
