serversocket and proxy

[cod3nam3]

Hi, i have a small prog. where i am listining on a port for
connections:

        ServerSocket serversocket = null;
        listening = true;
        try
        {
            serversocket = new ServerSocket(64111);
            serversocket.setSoTimeout(1000);
        }
        catch(IOException ioexception)
        {

        }

        Socket socket = serversocket.accept();

The prog works fine outside of a proxy, fails behind one. I need
somehow to tell the socket to use a proxy on port 80. Someone have an
idea?

Use this code:

System.setProperty("socksProxyHost","some.socks.host");
System.setProperty("socksProxyPort","some.socks.port");

for a SOCKS proxy and

System.setProperty("http.proxyHost","some.http.proxy.host");
System.setProperty("http.proxyPort","some.http.proxy.port");

for a HTTP socket. The latter will of course only work with HTTP
requests as done via the URL class.

I meant to say "HTTP proxy" instead of "HTTP socket" but you figured
that out yourself already, I guess.

You need to tell the *clients* about the proxy. Not this server code.

And as EJP noted: proxies are used from the client so my remarks are
meant for the client code connecting to your server.

You may be trying to do something that can only be achieved with a
reverse proxy but that is a completely different thing.

Please give us more details about what you are trying to do.
