+* HttpService is a server side HTTP protocol handler based in the blocking
+* I/O model that implements the essential requirements of the HTTP protocol
+* for the server side message processing as described by RFC 2616.
+* <br>
+* HttpService relies on {@link HttpProcessor} to generate mandatory protocol
+* headers for all outgoing messages and apply common, cross-cutting message
+* transformations to all incoming and outgoing messages, whereas individual
+* {@link HttpRequestHandler}s are expected to take care of application specific
+* content generation and processing.
+* <br>
+* HttpService relies on {@link HttpRequestHandler} to resolve matching request
+* handler for a particular request URI of an incoming HTTP request.
+* <br>
+* HttpService can use optional {@link HttpExpectationVerifier} to ensure that
+* incoming requests meet server's expectations.
