403 prohibition is the status code in the HTTP protocol. It can be simply understood as having no right to enter this station. This status indicates that the server understands the request but refuses to perform the task, and the request should not be retransmitted to the server.
When the method of HTTP request is not "HEAD", the server wants the client to know why there is no permission, and the server should describe the reason for rejection in the returned information. In the case that the server does not want to provide any feedback information, the server can replace 403 prohibition with 404 Not Found.
