Prevent 172.16.100.56 from sending invalid HTTP requests to your Squid
server. Pulling the Ethernet cable, shutting the switch port or adding
a software firewall rule preventing communications from this host are
all valid (though, nuke-it-from-orbit) methods of achieving this goal.

Identifying the application on this host that is sending the non-HTTP
data to your Squid server and configuring it such that it refrains is
probably a more prudent approach.
