 /**
  * 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.
