Can PHP use curl to send requestheader and then download the file directly?

PHP uses curl to send the cookie, referer, and other requestheaders before the location jump. Does the session server receive the requestheader? If not, how can I directly download the text that requires cookie verification through PHP without setcookie on the server...

If the server does not have a setcookie, how can I directly download the files that require cookie verification to the client through PHP.
My previous idea was to send a cookie to the server through php curl, and then redirect the header location. Unfortunately, no.

I am doing this to enable flash/html5 to play the video files that require cookie verification without setcookie on the server.

Since the server does not have a secookie, what should I use to verify the cookie? You have the problem described.
