Class HttpConnection

java.lang.Object
  org.mortbay.jetty.HttpConnection

All Implemented Interfaces:

Connection

public class HttpConnection
extends Object
implements Connection

A HttpConnection represents the connection of a HTTP client to the server and is created by an instance of a Connector. It's prime function is to associate Request and Response instances with a EndPoint.

A connection is also the prime mechanism used by jetty to recycle objects without pooling. The Request, Response, HttpParser, HttpGenerator and HttpFields instances are all recycled for the duraction of a connection. Where appropriate, allocated buffers are also kept associated with the connection via the parser and/or generator.
