Question about using socket WITH proxy server

[bl...@torfree.net]

Hello,

I have a simple app using socket to talk to a POP3/SMTP server on Internet. It
works fine in most cases. Currently, whern I use the same program at work
where a proxy server is used company wide and I found CSocket::Connect(
server, port) couldn't make a connection at all. It always returns me timeout
finally.

However, programs like Netscape still works once I specify the proxy server
for it.

Now, my question is how can I configure the socket using a proxy server so
that I still can talk to Internet servers outside? I didn't see any API
dealing with proxy server or anything like that.

Any idea?

Go to http://info.internet.isi.edu/1/in-notes/rfc and read e.g. RFC 1928.

Basically you connect to the proxy, authenticate yourself and tell the proxy
where to connect to. Then you use the connection as if it was direct, the proxy
server relays everything sent both ways.

Erik.
