Shunting downloaded pages

[Chip Seraphine <chip@xxxxxxxxxxxx>]

I am interested in using Squid as a sort of "recorder" for web- 
browsing sessions.  Specifically, I am interested in running a script  
on every HTML page downloaded (for use in assembling maps in a  
browser game).  Is there any way I can do this?  I'd love to simply  
have the pages appear as files in a directory somewhere or the like,  
so that I could process them later....
