I've read the various questions tagged [ssl] and [mitm] and [proxy] and I couldn't find a duplicate. I cannot find any documentation on this subject online.
All of the traffic is currently flowing through the firewalls, from here if it is port 80 or 443 then it is being pushed through to a web filtering system. The WEb Filtering system currently does SSL inspection, but the firewalls don't. What would be the impact if I performed SSL Decryption at both the firewall level, and also at the Web Filtering level ?
Would the target URL be aware that multiple SSL Interceptions have happened?
