htaccess file question for exceptions

[eluser]Julian_Omaha[/eluser]
So, I have a controller that I do not want to include in the htaccess redirect to index.php?/.

I am unfamiliar with how to set up my htaccess file to allow that to happen. I want all requests for (www.website.com/index.php?/) to be routed correctly to (wwww.website.com) EXCEPT www.website.com/index.php?/mobile/...

Make sense? Help please!
