Re: [squid-users] TCP_DENIED/403 errors when ads blocking is activated

You're right, Matus. That was the issue. I replace as you suggested: acl ads dstdom_regex "/etc/squid/ad_block.txt" by acl ads dstdomain "/etc/squid/ad_block.txt" and now it works. Thank you very much, Matus ! Have a nice day. Nicolas. Le 03/12/2022 à 15:02, Matus UHLA

[squid-users] Replace SquidGuard with ufdbguard : configuration examples ?

Hi, I've been running the Squid + SquidGuard combination for quite some time in our local school. I'm also filtering HTTPS connections using the Squid SSL Bump functionality. I'd like to test ufdbguard, since SquidGuard doesn't seem to be maintained anymore, and it's also quite RAM-consuming.
