   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.
