How can I log in to remote site with PHP cURL, then redirect to that site

[Amour]

I've seen this asked in several ways but can't find an answer that works. I've created a page that logs into a remote .NET-based site using PHP/cURL. Works great as far as it goes -- I can get the data back from the logged-in page via curl_exec and do whatever with it but what I really need to do is to redirect the user to that page. Simply redirecting gives me a logged-out page on the remote site. I know the answer is in getting the cookie that's returned when cURL logs in, then passing it in a second call . . . somehow. I;m certain that someone must be doing this and can provide a working example. Please help -- this is driving me nuts! Thanks,Mark
