HttpRequestHandler represents a routine for processing of a specific group
of HTTP requests. Protocol handlers are designed to take care of protocol
specific aspects, whereas individual request handlers are expected to take
care of application specific HTTP processing. The main purpose of a request
handler is to generate a response object with a content entity to be sent
back to the client in response to the given request
