Another incredibly common question, I'm sure.
I've found so many resources discussing this, but they're all so different that it makes it difficult to know (or test) to see which works.
I would like a user to go to an address on my server eg "www.blah.ccom/download.php?filename=blah.zip
" and their browser starts downloading the file without them knowing the actual location of the file on the server.
I understand that it has something to do with headers, but apart from that, I'm befuzzled from the shear amount of bad examples on the web!
Preferably should work with IE, using standard install of PHP 4.3.1.
