Possible to NOT force download with a particular file type?

[coinkydink]

Hi all,

I have a resources library that forcing the download on is perfect, and the script's working great. Many thanks.

However, a couple of the resources are php pages that obviously I don't want downloaded, I want opened.  I still want to count the click through though, so adding an if to the download link is impractical.  Can anyone advise a mod to force download everything except named types?

Thanks in advance.
