*
* A HttpConnection represents the connection of a HTTP client to the server and
* is created by an instance of a {@link Connector}. It's prime function is to
* associate {@link Request} and {@link Response} instances with a
* {@link EndPoint}.
*
*
* A connection is also the prime mechanism used by jetty to recycle objects
* without pooling. The {@link Request},{@link Response}, {@link HttpParser},
* {@link HttpGenerator} and {@link HttpFields} instances are all recycled for
* the duration of a connection. Where appropriate, allocated buffers are also
* kept associated with the connection via the parser and/or generator.
