Public Member Functions
	HttpRequestHandler (QObject *parent=NULL)
virtual	~HttpRequestHandler ()
virtual void	service (HttpRequest &request, HttpResponse &response)

Detailed Description

The request handler generates a response for each HTTP request. Web Applications usually have one central request handler that maps incoming requests to several controllers (servlets) based on the requested path.

You need to override the service() method or you will always get an HTTP error 501.

Warning

Be aware that the main request handler instance must be created on the heap and that it is used by multiple threads simultaneously.
