Interface RequestHeader

public interface RequestHeader

The RequestHeader interface contains constants for HTTP request headers used by other HTTP Model-View-Controller classes.

When an HTTP client, i.e. a browser, sends a request to the server, that client is required to provide a request line (usually GET or POST). Additionally, that client may also send a number of request headers, all of which are optional except for Content-Length, which is required only for POST requests.
