squid Version 3.1.11, not transparent
1200 LAN clients surf the web thru the squid server. Browsers' configuration, programmatically pushed to clients, is
http server:3128 https ---
On the clients, we access http web sites thru squid, https web sites directly.
Some colleagues tweak their browser' configuration : they set the squid server also on https. So they broke their https surfing.
Question : is there a way to show an error message in this scenario ?
I want to prevent this kind of helpdesk calls !
The goal is to force squid and/or the browser to show a clear error page, like
Your browser configuration isn't correct. This proxy server only handles HTTP navigation.
