OpenSUSE Network :: When Try To Click On A .avi All It Wants To Do Is Download The Video Instead Of Playing It In The Browser?

i am currently using monkey webserver on my linux machine for my website. I just recently found out that you can also stream music if you direct the web address to a folder inside the directory. The problem is when i try to click on a .avi all it wants to do is download the video instead of playing it in the browser or playing it in windows media player. What can I do to make an .avi to stream from my linux machine ( note this is for private use only so i can stream movies on my lunch break or when I am at a friends house this is not to share my stuff to the general public)
