Problem with httpclient 3-x and socks server

[Seb <me...@hotmail.com>]

Hi,

I'm currently writing an application that needs to hit two different webapps, one using a socks server, and another one that does not need to use the socks server.
What I would like is to use the socks server only for the connection that needs it, and not for the other (because I want to avoid the eventual slowlinesses of the socks server).

According to the httpclient documentation, it seems that the only way to use a socks proxy is to set it up for the whole JVM (with socksProxyHost and socksProxyPort system parameters), what means that all HTTP connections will use socks :(

So my question is :
Is there a way to tell httpclient to build specific socks connections, as it is possible to do using the legacy java.net API ?
Example :
SocketAddress addr = new InetSocketAddress(host,port);
Proxy proxy = new Proxy(Proxy.Type.SOCKS, addr);
URLConnection conn = url.openConnection(proxy);
InputStream result = new DataInputStream(conn.getInputStream());

I've looked at the source code and I've finally found no way to be able to reach the socks server... I systematically get I/O timeout errors :(


Thanks a lot,
Sebastien.

Thanks a lot, it solved my issue !I've already tried to create a new ProtocolSocketFactory, but I did not knew anything about Protocol.registerProtocol() method :(Thanks,Seb> Date: Mon, 3 Mar 2008 17:38:51 +0100> From: ossfwot@dubioso.net> To: httpclient-users@hc.apache.org> Subject: Re: Problem with httpclient 3-x and socks server> > Hi Sebastien, Alan,> > Alan Moss wrote:> > You need to create your own custom ProtocolSocketFactory[1] and > > implement the createSocket methods in the manner you mentioned.

That's the idea, although I would move the if(...) part into the
socket factory. Things get ugly if you want to juggle between
different socket factories for the same protocol/scheme.

Alternatively, if you're on Java 5 or later, you might want to
install your own ProxySelector in the "legacy" java.net API :-)

You need to create your own custom ProtocolSocketFactory[1] and 
implement the createSocket methods in the manner you mentioned. Once you 
do that, you need to tell HttpClient to use it. Something like this:

     if (shouldUseSocks) {
         Protocol.registerProtocol("http",
             new Protocol("http", new MyProtocolScoketFactory(), 80));
     }

Good luck.
