How to add handler types?

[azn_romeo_4u]

Not sure if it's called handler or not...

I got a site that lets me download cursor files. But when they download it, the download box doesn't appear, instead it opens the cursor file and spits out the cursor text. Like if you were to open an image file in notepad it spits out the weird information stuff.

I remember I added it before one time through the admin cp but now I can't seem to find where to add it in. I need to tell litespeed that a cursor is an ico or an image or whatever...and not text.
