I'm not sure if that is the right module to use, since I cant find a clear documentation on that one.
You could try a different URL Rewrite module:
Some documentation I found on this module:
Depending on how you want to use the rewrite module, you could also look into the IIS url rewrite options: www.iis.net/.../url-rewrite
With the IIS option you can set the rewrite rules in config files, or use IIS to create the rules and test patterns.
I hope this helps.
