response. 10.1 Informational 1xx This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. There are no required headers for
Http Code 302
this class of status code. Since HTTP/1.0 did not define any 1xx status codes, 301 moved permanently wordpress servers MUST NOT send a 1xx response to an HTTP/1.0 client except under experimental conditions. A client MUST be prepared to
301 Moved Permanently Php
accept one or more 1xx status responses prior to a regular response, even if the client does not expect a 100 (Continue) status message. Unexpected 1xx status responses MAY be ignored by a user agent. https://en.wikipedia.org/wiki/HTTP_301 Proxies MUST forward 1xx responses, unless the connection between the proxy and its client has been closed, or unless the proxy itself requested the generation of the 1xx response. (For example, if a proxy adds a "Expect: 100-continue" field when it forwards a request, then it need not forward the corresponding 100 (Continue) response(s).) 10.1.1 100 Continue The client SHOULD continue with its request. This interim response is used https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html to inform the client that the initial part of the request has been received and has not yet been rejected by the server. The client SHOULD continue by sending the remainder of the request or, if the request has already been completed, ignore this response. The server MUST send a final response after the request has been completed. See section 8.2.3 for detailed discussion of the use and handling of this status code. 10.1.2 101 Switching Protocols The server understands and is willing to comply with the client's request, via the Upgrade message header field (section 14.42), for a change in the application protocol being used on this connection. The server will switch protocols to those defined by the response's Upgrade header field immediately after the empty line which terminates the 101 response. The protocol SHOULD be switched only when it is advantageous to do so. For example, switching to a newer version of HTTP is advantageous over older versions, and switching to a real-time, synchronous protocol might be advantageous when delivering resources that use such features. 10.2 Successful 2xx This class of status code indicates that the client's request was successfully received, understood, and accepted. 10.2.1 200 OK The request has succeeded. The information returned wit
of 301 tells a client that the resource they asked for http://100pulse.com/http-statuscode/301.jsp has permanently moved to a new location. The response should also include this location. It tells the client to use the new URL the next http://stackoverflow.com/questions/14369471/301-moved-permanently-where-is-the-new-link-to-the-redirect-page time it wants to fetch the same resource. Why it Occurs If a client has link-editing capabilities, it should update all references to the 301 moved Request URL. The response is cacheable.
