Re: [squid-users] Why squidguard or another redirektor???

Hi all,

Same requirement here too. We have used text files with url_regex to block
porn and warez sites. The text files contain over 40 k entries. If using
url_regex can affect performance, can I use acls based on dstdomain or dst
with text files ?

Thanks and regards,
Michael Fuller.
