Hi,
I've been running Squid successfully on CentOS 7 (and before that on 6 and 5), and it's always been running nicely. I've been using it mostly as a transparent proxy filter in school networks.
So far, I've only been able to filter HTTP.
Do any of you do transparent HTTPS filtering ? Any suggestions, advice, caveats, do's and don'ts ?
I did some experiments ~2 weeks ago. It worked, but I still need to work on the certificates. Squid will re-issue certificates for those connections that it intercepts, and if the browser doesn't recognize the CA, it's going to scream out loud. For the test, I imported my test CA in the browser and then was completely transparent. Not sure if there is a way to avoid this. I hope not, actually.
https://smoothnet.org/squid-proxy-with-ssl-bump/ was of good help to me, btw.
