Description

It would be very nice when Suricata can handle the ICAP protocoll for filtering decrypted SSL Web Traffic.

Proxies - for example Squid - often are doing SSL Inspection through local loopback interface (lo) ICAP Protocol on Port 1344.
I can configure Suricata to listen on "lo" Interface, but Suricata is not alerting the rules on this decrypted Web Traffic which is readable on lo interface also for suricata.

I guess suricata needs an "ICAP Wrapper", so a new feature?

Attached you'll see an example of the only Suricata alert i get sometimes while monitoring local loopback interface, on that all the decrypted web traffic goes through for virus scanning (custom port 13444 instead of 1344). I should see much more alert hits from suricata, so suricata seems not to understand ICAP yet.
