Serving an external web site which requires authentication

[Kaze]

Hi,

I need your suggestions about the topic.
Actually, I'm not sure where to start but basically, I want to make
something like;
(I have an account on a site which requires log-in)

- I'll be logged-in to that site with my account in my server.
- And when a user connects to my site, I'll forward him/her to that
site, using my account even if he/she doesn't have an account on that
site...

probably, I need to develop a proxy to do this, but I'm not sure...
(I'm developing a django site)

I really appreciate your ideas.
