Remote Login to ASP site

edh

I have a site that I want to login into. It is an ASP site that uses server side sessions, because no cookies are set on the client side.

Is there a way to login to the remote ASP site using PHP. The login page, after authenticating redirects to the user area.

However, I am assuming that since a new session is created when PHP calls (fopen's) the site (even through redirect) that the ASP site can't authenticate and then loggs me out.

Is there a way to keep the same session going to keep authentication accurate on the ASP site so that I can access the user area as intended?

Thanks,
