[Wolves] Apache question

[James Turner]

Like all things, it's probably dead easy if you know how, but...

One of my friends is working on a web site which amongst other things will 
include a section that provides (legal) MP3s for download. How do you ensure 
that when a user clicks on a link to one of the MP3 files their browser 
always begins to download the file rather than trying to load it into a media 
player (etc)?

As a temporary measure, he is providing users with instructions to right-click 
on the links and select "Save link target as..." (or whatever the IE 
equivalent is) but it would be far better if they could just left-click. Does 
the solution lie in something to do with setting the content type?

The web server is currently running Apache 1.3 on FreeBSD.

Thanks,

James
