Anyone have a idea on how to Mod Rewrite this string?

http://www.websitehostdirectory.com/...oad&/Business/

In this string the entire URL is constant up to the "/Business/" , That is the portion of the URL that will change when a user clicks else where.

Any ideas how to make it something like this:
