+ * <tt>HttpService</tt> is a server side HTTP protocol handler based on
+ * the classic (blocking) I/O model.
+ * <p/>
+ * <tt>HttpService</tt> 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 implement
+ * application specific content generation and processing.
+ * <p/>
+ * <tt>HttpService</tt> uses {@link HttpRequestHandlerMapper} to map
+ * matching request handler for a particular request URI of an incoming HTTP
+ * request.
+ * <p/>
+ * <tt>HttpService</tt> can use optional {@link HttpExpectationVerifier}
+ * to ensure that incoming requests meet server's expectations.
