Dynamic Redirect

[nate]

I was wondering if there is a way to redirect a url other then the old traditional way of creating a sub folder and an index page with a redirect. Basically I want to do something like this:

 

http://www.mysite.com/123 and have it redirect to something else like http://www.mysite.com/987349872345324 but I do not want to have to create a sub folder with an index page that handles the redirect.

 

Any help would be great.

 

P.S. I would love to do it without using variables like http://www.mysite.com/?var=123

 

Thanks in advance.
