I have a website, a.b.hotgirls.com, with a link that users will download from, c.hotgirls.com. When clicking on a link like c.hotgirls.com/pics.run, the link renders the file in a separate tab depending on the user's preferences. For other extensions like c.hotgirls.com/pics.dmg and c.hotgirls.com/pics.exe, the link to the file downloads properly.
I'd like for the click on c.hotgirls.com/pics.run to automatically download the link to the file. How shall I go about this?
