specification, the browser even if the original request is post will automatically redirect, resulting in the specification and implementation of two semantics, resulting in a number of issues, such as 302 hijacking, so in the HTTP 1.1 The specification of 302 is refined into 303 and 307, in the hope of eliminating ambiguity.Supplement: 302 hijacking--a station by redirecting to B station Resources Xxoo,a station actually did nothing but a friendly d

, then the browser disables automatic redirection unless the user confirms it, because the requested condition may vary. Note: Although the RFC 1945 and RFC 2068 specifications do not allow the client to change the method of the request during redirection, many existing browsers treat the 302 response as a 303 response, and use GET to access the URI specified in the location, ignoring the method originally requested. Status Codes

Cache-control or expires. The new temporary URI should be returned in the location domain of the response. 　　Unless this is a HEAD request, the response entity should contain a hyperlink to the new URI and a short description. 　　If this is not a GET or HEAD request, then the browser disables automatic redirection unless the user confirms it, because the requested condition may vary.

response, the next redirect request becomes a Get method.302 FoundThe requested resource is now temporarily responding to requests from different URIs. Because such redirects are temporary, the client should continue to send subsequent requests to the original address. This response is cacheable only if specified in Cache-control or expires.The new temporary URI should be returned in the location domain of the response.

, many existing browsers treat the 302 response as a 303 response and use get to access the URI specified in the location, ignoring the method originally requested. Status Codes 303 and 307 are added to clarify how the server expects the client to react. The corresponding status information in HTTP1.0 is Moved temporatily. When the status code appears, the browser can automatically access the new URL, so i

HTTP status Code editing The HTTP status code is a 3-bit numeric code that represents the HTTP response status of the Web server. It is defined by the RFC 2616 specification and is extended by RFC 2518, RFC 2817, RFC 2295, RFC 2774, RFC 4918, and other specifications.

(Request-uri) for future requests. The response is cached only when the Cache-control or Expires header field is described.The temporary URI should be provided by the location field in the response. Unless the request method is head, the responding entity should contain a short hypertext comment with a hyperlink to the new URI.If the request method that receives a 302 status in response to a request is not head or get, then the user agent cannot automatically redirect the request unless the use
