Problem with dansguardian
 

Dear all
I have configured my proxy with squid and dansguardian.Every thing is working fine.i am using ncsa authentication.Each client is given different ncsa usernames and passwords for authentication through proxy.i have also blocked some sites (orkut,gmail) etc and phrases (porn,sports) etc.Now the problem is i want to allow "orkut and gmail" for a ncsa user. How can i do this with dansguardian (keep in mind no need to allow banned phrases or other banned sites for that user )
Advanced Thanks
Ajay
