I don't see how you can parse such a list per user/HTTP request without
some amount of 'slowness'. See my previous post... Even with an URL
regexp file, squid process spends some amount of time in poll state
parsing >5k line text file.

Luckily, we have few users on the LAN, so this is not a significant issue.
How would a large company handle this? I used squid briefly in my ISP
days (30k+ dialup users)... just not this functionality. Mostly
because banner ads weren't such a nuisance then! There has to be ways of
accomplishing this more efficiently. Perhaps patches to squid source that
compile the regexp list into an internal hash? I suppose that would be an
extreme of just opting for something like SquidGuard which do DB lookups.
