Constantly reconfiguring Squid has a large number of side effects such 
as the one you noticed. Avoiding that is a good idea.

I recommend having a table in the database with the details about 
whether a user is allowed (or not). The ext_sql_session_acl helper can 
check that table to allow/deny users.
