No-cache: The request is sent first to confirm with the server whether the resource has been changed. If it has not been changed, the cache is used. No-store: no caching is allowed. Go to the server every time and download the complete response. Public: Cache all responses, but not required. The same effect can be achieved with max-age. Private: only a single user is cached. Therefore, no trunk is allowed to cache. (CDN, for example, does not allow caching of private responses.) MaxAge: Indicates how long it takes for the response to be cached and reused without a request to the server. For example, max-age=60 indicates that the response can be cached and reused for another 60 seconds. --> <meta http-equiv="cache-control" content="no-cache"> <! <meta http-equiv=" Expires "content="Sunday 26 October 2016 01:00 GMT" /> <! <meta http-equiv="refresh" Content ="2000" URL=http://www.lxxyx.win/"> <! -- set-cookie, if the page expires. <meta http-equiv=" set-cookie "content="User=Lxxyx; path=/; expires=Sunday, 10-Jan-16 10:00:00 GMT"> <! --> <title> <title>Copy the code
