current links or records using the URL that the response is received for should be updated. The new http error 302 URL should be provided in the Location field included with the response. The 301 redirect is considered a best practice for upgrading users from HTTP to HTTPS.[1] RFC 2616 states http error 304 that: If a client has link-editing capabilities, it should update all references to the Request URL. The response is cachable.[2] Unless the request method was HEAD, the entity should contain a small hypertext note with a hyperlink to the new URL(s). If the 301 status code is received in response to a request of any type other than GET or

HEAD, the client must ask the user before redirecting.

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 http error 401 no required headers for this class of status code. Since HTTP/1.0 did not http error 500 define any 1xx status codes, servers MUST NOT send a 1xx response to an HTTP/1.0 client except under experimental

conditions. A client MUST be prepared to 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 https://en.wikipedia.org/wiki/HTTP_301 1xx status responses MAY be ignored by a user agent. 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 https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html 100 Continue The client SHOULD continue with its request. This interim response is used 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 Succ
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/1393280/http-redirect-301-permanent-vs-302-temporary 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 http error Request URL. The response is cacheable. Unless the request method was HEAD, the entity should contain a small hypertext note with a hyperlink to the new URL(s).If the 301 status code is received in response to a request of any type other than GET or HEAD, the client must ask 301 http error the user before redirecting. Fixing 301 Error Code If the Web server does not return an alternative URL with the 301 response, then either the Web server sofware itself is defective or your Webmaster has not set up the URL redirection correctly.

The client/browser should not attempt to request the original location but use the new location from now on. Status 302 means that the resource is temporarily located somewhere else, and the client/browser should continue requesting the original url. share|improve this answer edited Sep 8 '09 at 11:05 answered Sep 8 '09 at 10:51 Philippe Leybaert 98.3k22172202 62 +1 for being simple and clear and not just reiterating the RFC –David Z Sep 8 '09 at 11:02 7 Thank you. Does this mean that if I use a 301 (permanent) redirect, the client can decide to never again retrieve the old location and instead always use directly the new URL? –flybywire Sep 8 '09 at 11:39 11 Exactly! In fact, according to the specs, the client SHOULD always go to the new location. –Philippe Leybaert Sep 8 '09 at 11:45 4 But in a browser, how does this affect? Rewriting the history in the back button for example, to avoid going back to the wrong one in a 301
