## 501 - Header values specify a method that is not implemented.

### The page you are looking for cannot be displayed because a header value in the request does not match certain configuration settings on the Web server. For example, a request header might specify a POST to a static file that cannot be posted to, or specify a Transfer-Encoding value that cannot make use of compression.
