Hello Amos!

I do not have via off in my squid.conf, so i think it is set to on, default value.

Otherwise, i redirect outbount http/80 to the internal 8080 on firewall/squid machine.
It seems from a specific client someone try to pass an exploit to the 8080 port...

What else should i consider?

Thank you again!
