Subject RE: HttpCore NIO & SSL behind proxy
Date Mon, 19 Jul 2010 14:04:10 GMT
Thanks Oleg and Asankha.

So, as you known, in httpclientasync, I changed the dispatcher to SSL and after the first
request (or a while), it gets stuck not publishing the next request.

After analyzing and comparing HTTP vs HTTPS logs, actually, I may have found my mistake. Changing
to SSL dispatcher seems not enough; I must also set the SSL session to the OP_WRITE event
in addition to the regular session (in HttpExchangeImpl.requestCompleted):

  private synchronized void requestCompleted(final ManagedIOSession session) {
    this.managedSession = session;
    IOSession iosession = session.getSession();
    iosession.setAttribute(InternalRequestExecutionHandler.HTTP_EXCHANGE, this);
    SSLIOSession sslsession = (SSLIOSession) iosession.getAttribute("SSL_SESSION");
    if (sslsession != null) {

I guess that comes probably from the way SSLIOSession decorates the iosession.

Am I right? Is it the correct way to do it?

FYI, to achieve SSL as well as HTTP in httpclientasync, I actually made InternalClientEventDispatch
a composite of DefaultClientIOEventDispatch and SSLClientIOEventDispatch, forwarding to the
right one depending on the scheme of the target host.

You could also try the "-Djavax.net.debug=all" system property, which 
may give you a hint if the cause is SSL specific
