Hi Amos,

AFAIK, the directive 'tcp_outgoing_tos' is applied only for traffic
from Squid to origin servers.

The reference [1] and my quick test confirmed my expectations:

  Allows you to select a TOS/Diffserv value for packets outgoing
  on the server side, based on an ACL.

Nevertheless, the directive 'qos_flows' [2] could be used to set ToS
for traffic from Squid to client.
