Easy script needed... Can you help?

[skylark]

I am looking for a script that to me seems like it would be very easy to make. I dont know if it would be cgi, php or even maybe even just plain ole java. I know what it might look like, and I know what I want it to do but I dont know how to write script. I know the first thing is that I need to learn to write script, but I also know there is someone out there that already has the script or can easily write it for me(which I would greately appreciate).

I want the script to work so that when someone accesses my index.html file it will read the url in the window address bar and then redirect them to a folder from there.
What I think it might look like is:
if window.url="http://www.gothere.com" goto="http://0.0.0.0/gothere/index.html
and if window.url="http://www.getit.com" goto="http://0.0.0.0/getit/index.html
etc etc

The reason for this is that I have 5 domain names, all pointing to my ip htdocs folder, I for now have simply put up a link from there to the sites that Im hosting, however this seems tacky when you want to go to getit.com and you end up on a page with 5 other names and you're being asked to click the link you want to visit. But technically the folders are mearely one folder under the index. being http://0.0.0.0/folder1/index.html.

I think this is a very easy script but I may be wrong. It's happened like once before...haha

Any help or even a response would be greatly appreciated.
