I have implemented a transparent squid3 proxy for logging purposes.
I won't be doing SSL bumping / HTTPS decryption, as this is too much to install a cert on every client.
However, I would like to log the CONNECT
URL data passed to squid. For some reason, it doesn't log even the root domain on HTTPS requests, when these definitely hit squid.
Is there any way to do this?
