I worked on a script like yours for a looooooooooong time now!
I need to force the download of various type of file, doc, pdf, zip, even
html!
Your script works fine on Opera 5.02 and netscape 4.76 on my win NT 4.0 box,
but
not on IE 5.5 On this one, it offers me to download the script file but
instead of being
a php file it has now an html extension !!
Anyhow, I do have a download by email attachment button also, because I gave
up on trying
to find a script to force download....
