Norbert, I think a better idea would be to add this method in the
SslFilter class :
/**
* Initiate the SSL handshake. This can be invoked if you have set
the 'autoStart' to
* false when creating the SslFilter instance.
*
* @param session The session for which the SSL handshake should be done
* @throws SSLException If the handshake failed
*/
public void initiateHandshake(IoSession session) throws SSLException {
IoFilter.NextFilter nextFilter =
session.getFilterChain().getNextFilter(SslFilter.class);
initiateHandshake(nextFilter, session);
}
You can now call it from your handler doing :
@Override
public void proxySessionOpened(IoSession session) throws Exception {
log.info("proxySessionOpened called");
if (sslFilter != null) {
sslFilter.initiateHandshake(session);
}
}
That removes the burden of finding the next filter in the handler.
wdyt ?
