Provides a mechanism to send a response to a request.

This class is created internally by the Web Server and thus cannot be created from outside code. To handle requestsList and response, the WebServer.IHTTPRouteHandler interface or the delegate methods in RouteSolver which is available from the WebServer.WebServer.Routes property.

When using a method such as WriteString, WriteHTML, SetHeader, etc., no data is actually sent to the client. Instead, data is buffered until the RouteSolver is done processing, which will automatically send the response to the client.
