Preface: A HTTP status code is issued from the server in response to a client's request made to the server. The five status code response classes are informational, successful, redirection, client error and server error.
Redirection status codes
Redirection status codes are returned when a new resource has been substituted for the requested resource. To complete the request, further action must be taken.

300 Multiple Choices
Definition: The request has more than one possible response. The user-agent or client should choose one of them. There is no standardized way of choosing one of the responses, but HTML links to the possibilities are recommended so the user can pick. For example, this code could be used to present multiple video format options, to list files with different filename extensions, or to suggest word-sense disambiguation.
300 Multiple Choices
is defined in RFC 7231.
301 Moved Permanently
Definition: The request is looking for a resource that has moved permanently. Its new URL is given in the response.
301 Moved Permanently
is defined in RFC 7231.
302 Found
Definition: The request is looking for a resource with a URI that has been changed temporarily. Further changes in the URI might be made in the future. The current URI should be used by the client in future requests.
302 Found
is defined in RFC 7231.
303 See Other
Definition: The request is looking for a resource that can be found at another URI using a GET
method. When received in response to a POST
, PUT
or DELETE
, it should assumed that the server has received the data and the redirect should be issued with a separate GET
message.
303 See Other
is defined in RFC 7231.
304 Not Modified
Definition: The request is looking for resource that hasn't been modified since the last time the client accessed it, so the client can continue to use the same cached version of the response.
304 Not Modified
is defined in RFC 7232.
305 Use Proxy
*
Definition:* The request is looking for a resource that must be accessed by a proxy. It has been deprecated due to security concerns regarding in-band configuration of a proxy.
305 Use Proxy
is defined in RFC 7231.
306 (Unused)
Definition: This response code is no longer used; it is just reserved. It was used in a previous version of the HTTP/1.1 specification.
306 (Unused)
is defined in RFC 7231.
307 Temporary Redirect
Definition: The request is looking for a resource that is currently redirected. The server sends this response to direct the client to get the requested resource at another URI with same method that was used in the prior request. Future requests can still use the original URI. 307 Temporary Redirect
has the same semantics has the 302 Found
response code, with the exception that the user agent must not change the HTTP method used: If a POST
was used in the first request, a POST
must be used in the second request.
307 Temporary Redirect
is defined in RFC 7231.
308 Permanent Redirect
Definition: This means that the resource is now permanently located at another URI, specified by the Location:
HTTP Response header. This has the same semantics as the 301 Moved Permanently
HTTP response code, with the exception that the user agent must not change the HTTP method used: If a POST
was used in the first request, a POST
must be used in the second request.
308 Permanent Redirect
is defined in RFC 7538.
Unofficial and customized non-standard responses defined by server softwares are not included in the list above.
