httpclient 3.0 - SOCKS Proxy Support

Hi,

My understanding looking at the httpclient 3.0 features was that SOCKS 
proxy support was integral part of the code.
However, I don't see any API which can take a Proxy object as argument 
and create a socket using jdk 1.5's
SOCKS support.

Kindly clarify how SOCKS is supported in 3.0

Thanks a lot.

- Chandra

Chandra,

There is quite a few samples in the HttpClient contrib package. They are
all mainly SSL related, though:

http://svn.apache.org/viewcvs.cgi/jakarta/commons/proper/httpclient/trunk/src/contrib/org/apache/commons/httpclient/contrib/ssl/

This one is probably closer to what you are trying to do:

http://svn.apache.org/repos/asf/jakarta/jmeter/branches/rel-2-1/src/core/org/apache/jmeter/util/SlowSocket.java
http://svn.apache.org/repos/asf/jakarta/jmeter/branches/rel-2-1/src/protocol/http/org/apache/jmeter/protocol/http/util/SlowHttpClientSocketFactory.java

Please in the future do respond to the mailing list, not to me directly

Cheers,

Oleg

HttpClient does not support SOCKS proxying directly. However, it can
make use of whatever support the JRE provides. if the underlying JRE is
capable of opening sockets via a SOCKS server, so is HttpClient.  

One can also consider implementing a custom socket factory that makes
use of jdk 1.5 functionality and registering it as a default protocol
socket factory for the desired protocol scheme.

Hope that clarifies things a little
