What do you mean by "transparent"? that affects how you do things. A lot.

It seems that you don't mean transparent interception. Unless your
firewall config was intercepting ports other than 80.

broken config right there.

correct config is two separate lines:
  http_access deny !Safe_ports
  http_access deny CONNECT !SSL_ports

Specifically;
 * block ALL access to unsafe ports (mail servers etc).
and
 * block binary CONNECT tunnels to non- SSL-encrypted ports.

CONNECT method is not permitted direct to origin servers. That request was
intended for a proxy. So what you meant by "transparent" is very important.
