[K12OSN] Squid proxy filter behind an N2H2 proxy filter

Joy and Peace to you, and don't get the flu !!!
Question: Our district currently sits behind an N2H2 filter from our ISP 
and it does a great job.  Problem:  The block policy does not include game 
download sites.  ( I love games - but school it not the place ;)   )   I 
would like to place a Squid filter at my head end to block certain items 
locally that my ISP will not block.  To the question - Has anyone done this 
?  A proxy filter behind a proxy filter ?  I would use the N2H2 filter as 
it sits with her current policies, and add the Squid box to monitor traffic 
and block the game sites as they become discovered.  I don't want the Squid 
proxy to pass through N2H2 but exist as a second line of defense.  I don't 
think I need to cache, just filter/monitor.  155MB OC3 to T3  CS anyone !

Boy does this post sound like "Big Brother is watching"  yikes...

- LTSP 4 -  a fine example of human ingenuity. I can't wait for my ISO's. 
Fine fine work.  The students who work with me are very excited.
