the 302 response as a 303 response, in addition, the GET method is used to access the URI specified in Location, regardless of the original request method. Status Codes 303 and 307 are added to specify the response that the server expects from the client. 303 The response corresponding to the current request can be found on another URI, and the cli

Discussion: the real strength of GCD can be seen only when code blocks are asynchronously executed on the main queue, serial queue, and concurrent queue. To execute asynchronous tasks on the dispatch queue, you must use one of the following functions: Dispatch_async submits a block object to the dispatch queue for asynchronous execution (both items are specified by parameters) Dispatch_async_f submits a C function and a context reference to the dispatch queue for asynchronous execution (three it

temporarily responds to the request from different Uris. As such redirection is temporary, the client should continue to send future requests to the original address. This response can be cached only when cache-control or expires is specified. The new temporary URI should be returned in the response location domain. Unless this is a head request, the response entity should contain hyperlinks and brief descriptions pointing to the new Uri. If this is not a get or head request, the

continue to send future requests to the original address. This response can be cached only when cache-control or expires is specified. The new temporary URI should be returned in the response location domain. Unless this is a head request, the response entity should contain hyperlinks and brief descriptions pointing to the new Uri. If this is not a get or head request, the browser prohibits automatic redirection unless it is confirmed by the user because the request conditions may change. Note:

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. 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
