Hi Amos, Thanks for that. Yes I understand the legalities, this isn't to 'forge' anything. The users are well aware they're not looking at the real sites. The CA will be installed on their systems and they will have to agree to it. The issue is that the browser is complaining that the CN does not match because my local web server that represents ANY site has a catch all CN. Therefore I'm trying to determine a way to generate the correct CN before Squid tries to bump the SSL so that the CN is nearly correct. The certificates I generate don't need to look like the original because I'm not trying to trick anyone, they just need not to error in the browser.
