I've been searching the Java net documentation and I found a few
interesting things:
First, it appears as if NTLM authentication was added to J2SE in
version 1.5.0_08.
http://java.sun.com/j2se/1.5.0/ReleaseNotes.html
http://java.sun.com/javase/6/docs/technotes/guides/net/http-auth.html
Second, as of 1.5.0, Sun added a Proxy class that allows you to
create a socket that talks through a Proxy:
http://java.sun.com/j2se/1.5.0/docs/guide/net/proxies.html
So my question is, with these J2SE technologies available, do they
accomplish what the Apache ProxyClient class does for me, i.e.,
tunnel a secure socket through any type of proxy (Basic, Digest,
NTLM) with relative ease? I've looked over the Apache code and I
find it very clean and impressive, but I wonder if it's worth the
additional jar dependencies if I can get the same work done through
the standard J2SE? ProxyClient apperas to do everything for you,
including figuring out the type of proxy and making the connection
behind the scenes. There may be a bit more work involved in the J2SE
approach (i.e. figuring out for yourself what type of proxy is
involved). I would appreciate any input from others who have looked
at this situation.
Thank You,
Eric

Hmmm, I may have answered my own question. It appears
org.apache.commons.httpclient.ProxyClient is what I need.

Hello,
Please excuse this potentially naive question, but I have been
searching the HTTPClient codebase today and I can't seem to put my
finger on where I can 'plug' into the code to take advantage of
the Proxy connection and authentication pieces only. In other
words, I don't want to use the HTTPClient class to send/receive
data, I want to use my custom Socket connection as-is.
My existing Proxy code looks like this:
Socket tunnel = new Socket(proxyHost,
proxyPort.intValue());
doTunnelHandshake(tunnel, serverAddress,
clientRequestsListeningPort);
Socket clientRequestsSocket =
((javax.net.ssl.SSLSocketFactory)sslSocketFactory()).createSocket
(tunnel, serverAddress, clientRequestsListeningPort, true);
... from here on I use my own input/output streams...
Where 'doTunnelHandshake' is my custom Proxy connection code which
is turning out to be way too simplistic (i.e. doesn't support
Digest, NTLM, or Custom authorization). Can anyone give me a
quick heads up on where I can start to convert this code to use
the Proxy authentication in HTTPClient and then communicate over
my socket as I normally would?
Thank You,
Eric
