please help me !



says it is unable to connect to that page. your ???.com name does not exist, or so it says.
I'm pretty sure he just made up the domain name to demonstrate, Skeletor.

Anyway, phptesthead, could you maybe restate your question? As it is, it's pretty unitelligible. For example, what do you mean by "make loads of pages"?
It's called a META refresh. It goes like this:

<meta http-equiv="refresh" content="5;URL=">

Put it between the download page's <head></head> tags and it will start downloading the file (e.g. "") in 5 seconds (change 5 to whatever you want, but it should be at least 2 or 3 to allow the page to load). And, of course, PHP can be used to replace "" with whatever file the user requests.
