Redirecting User depending on Group Membership

 Hi,
I have two user groups set up in AD and Im "authorizing" against these in my web.config file :
<authorization> <allow roles="CD"></allow> <allow roles="Individual"></allow> <deny users="*"></deny> </authorization>
 
What I need to do is redirect the user if they are a member of "CD" or "Individual".
 
Is this possible??
 
Thanks
