exposed according to the semantics of the HTTP method, then the interface will have security and idempotent features , such as get and head requests are safe, no matter how many times the request does not change the server state. The, put, and delete requests are idempotent, regardless of how many times the resource is manipulated, and the result is always the same, and subsequent requests do not have more impact than the first time.The following is a list of typical uses of Get,delete,put and

Note that vm. the default behavior of swappiness = 0 has been modified. if you continue to set vm. swappiness = 0, which may cause system memory overflow and cause MySQL to be killed unexpectedly. In the previous MYSQL optimization three axes on LINUX, we recommend that you set vm. swappiness = 0. To avoid swap out MySQL server memory. In this way, L

During debugging, the bug code always causes my web server to return an HTTP status code of 500, which is a general indication of an internal server error.

Redirection of HTTP 301,302,303,307 (RPM)(2012-12-11 11:55:04)reproduced Tags: gossip Category: Network 301 permanent redirection, which tells the client to be accessed from the new address later.302 as the standard of HTTP1.0, formerly known as moved temporarily, is now called found. Now using only for compatibility processing, including PHP's default location redirection is also 302.But HTTP 1.1 has 303 and 307 as a

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. 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

1. Description of the problem After the HttpServlet request is received and logically processed, it is redirected to another web system across the domain, and the form data is submitted as a post. 2. Problem solving This problem mainly addresses redirection, calling the HttpServletResponse object's Sendredirect () method, which is actually doing the following two things: 1. Set the status in the HTTP response header to 302;2. Set the location value in the HTTP response header to the specified U

URL.· 302-found is similar to 301, but the new URL should be treated as a temporary alternative, not permanent. Note that in the HTTP1.0 The status information should be "moved temporatily".
