How do I track the bandwidth used by a visitor?

I need a way to track the bandwidth used by a visitor who signed up to my website.

That would include images and movies. I could just fetch the filesize and add to the current number but what I'm wondering is how do I track a partial download in case of a partial movie download?

Thanks.

Your approach for files sounds good but I don't think there is anyway to find out how much of a file has been downloaded when the user cancels it.

Doesn't Apache have something to do with loggin everything?

Would it be possible to log all users operation into a specific file then read that log for the amount transferred?

Or any other imaginative ways?

Thanks.
