Subject Re: [httpclient] Proxy and release questions.
Date Mon, 04 Mar 2002 19:36:45 GMT
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.
