I guess you could implement an IoConnector to accompany your filter. The IoConnector would need a SocketConnector to delegate to. When connect() is called it will modify the remote address to point to the proxy instead and then call connect() on the SocketConnector. It would also add your proxy filter to the filter chain when a connection to the proxy has been established. The proxy filter would then take care of the authentication and initial handshake much like the SSLFilter does. Once the proxy has established a connection to the original remote address the proxy filter will have to notify the ConnectFuture returned by the proxy IoConnector and call sessionCreated/sessionOpened. -- Niklas Therning www.spamdrain.net
