As close as Rodney, or another committer coming up with a release plan.

Don't know for sure....can check if you don't want to scour the source.

I finally got the chance to test my theory and it works with JSSE1.0.2. I added the following
to HttpConnection (sorry, I'm working on Windows today and don't have a diff tool handy):
/**
* Return my alternative SSLSocketFactory.
* @return my alternative SSLSocketFactory.
*/
public SSLSocketFactory getSSLSocketFactory() {
return _SSLSocketFactory;
}
/**
* Set the alternative SSLSocketFactory.
* @param factory alternative SSLSocketFactory.
*/
public void setSSLSocketFactory(SSLSocketFactory factory) {
_SSLSocketFactory = factory;
}
...
/**
* Open this connection to the current host and port
* (via a proxy if so configured).
*/
public void open() throws IOException {
log.debug("HttpConnection.open()");
assertNotOpen(); // ??? is this worth doing?
try {
if (null == _socket) {
String host = (null == _proxyHost) ? _host : _proxyHost;
int port = (null == _proxyHost) ? _port : _proxyPort;
if (_ssl) {
//_socket = SSLSocketFactory.getDefault().createSocket(host,port);
if (_SSLSocketFactory != null) {
_socket = _SSLSocketFactory.createSocket(host,port);
} else {
_socket = SSLSocketFactory.getDefault().createSocket(host,port);
}
} else {
_socket = new Socket(host,port);
}
}
_input = _socket.getInputStream();
_output = _socket.getOutputStream();
_open = true;
} catch (IOException e) {
// Connection wasn't opened properly
// so close everything out
closeSocketAndStreams();
throw e;
}
}
...
/** My alternative SSLSocketFactory. */
private SSLSocketFactory _SSLSocketFactory = null;
I'm using the SSLTunnelSocketFactory code from the JDC Forum link I mentioned previously. It
works fine with both squid (http://www.squid-cache.org/) and muffin (http://muffin.doit.org/)
proxy servers.

dIon,
Thanks for the response. Let me at least partially answer my own question #2.
2. HttpClient does, in fact, support proxying (with a few caveats). You get
SOCKS support for free by setting the system properties socks.proxyHost and
socks.proxyPort and NOT setting the proxyHost and proxyPort in HttpConnection.
Non-SOCKS proxying works for HTTP but not HTTPS. Ari Luotonen outlines the
reasons why in his draft document "Tunneling TCP based protocols through Web
proxy servers" at
http://www.web-cache.com/Writings/Internet-Drafts/draft-luotonen-web-proxy-tunneling-01.txt.
So, it is necessary to "tunnel" through the proxy server. Pua Yeow Cheong had an
"Tips 'N Tricks" article in JavaWorld
(http://www.javaworld.com/javaworld/javatips/jw-javatip111_p.html) that covers
this as does the following post in Sun's Java Developer Connection -
http://forum.java.sun.com/thread.jsp?forum=2&thread=172538. It seems like it
should be possible to add getter/setter methods to HttpConnection for a property
that specifies an alternative SSLSocketFactory. I haven't had the time to try it
yet.
