Download File From Remote Server

Hi
I need to make a script to download files from a remote webserver.
The files will be approximately 200 MB.
How can I do this, and (I'm not sure if it's possible, but) how can I download files from a site that requires me to login before downloading.
I've used cURL before to post form data but I'm not sure if it can download binary files after logging in.

Sure you can. You just need to make sure to send the session cookie along.

Ok thanks, how would I do that?

Either cURL does it by itself, if it can handle cookies, or you process the Set-Cookie header that comes with the login response and send it along with the download request using the Cookie header.
