It serves as a support for various authentication mechanisms which are important to control access to pages and other resources as well. All of these mechanisms are based on the use of the 401 status code. The HTTP WWW-Authenticate response header defines the authentication method that ought to be wont to gain access to a resource. As discussed earlier, the WWW-Authenticate header is sent along with a 401 Unauthorized response.

For example, the server may decide to return a 401 response even for a valid, but un-privileged user. Or the server may return a 404 response ("Not Found") to hide the fact that the resource exists in the first place, typically if the user would also not be privileged to fetch the resource with a GET operation. \ No newline at end of file
