It was designed specifically to prevent interception attacks on HTTP traffic. One guess what transparent proxy does? To perform HTTPS interception you require software to do the interception (Squid + NAT). Install a SSL certificate in the Squid to name it the authoritative web server for every domain on the planet. Install another SSL certificate in the web browser of every visitor to let the clients web browser believe the false certificate you installed in the Squid. ...or trust that all your clients/visitors will simply click okay/accept at the security attack warning they get faced with. Done. You are now committing a felony crime in most countries. But never mind that. Amos
