WS?

[James!]

I'm wondering what exactly is a .ws file? I've seen some on Runescape homepage.

I want to know what it stands for, is there any tutorials on it, specific codes, specific stuff it's used for.

Reputation point to anybody that can help.

Dude, you can have whatever file extension you want.
Eg: index.joshilini

All you need to do is do some configuration in your mime types!
