All Implemented Interfaces:

org.jboss.netty.channel.ChannelHandler, org.jboss.netty.channel.ChannelUpstreamHandler, ConnectionData, RelayListener

public class HttpRequestHandler
extends org.jboss.netty.channel.SimpleChannelUpstreamHandler
implements RelayListener, ConnectionData

Class for handling all HTTP requests from the browser to the proxy. Note this class only ever handles a single connection from the browser. The browser can and will, however, send requests to multiple hosts using that same connection, i.e. it will send a request to host B once a request to host A has completed.
