Client get HTTP Via header even if defined "via off"

["Itzcak Pechtalt" <itzcak@xxxxxxxxx>]

Hi
squid.conf state the following:

#  TAG: via     on|off
#       If set (default), Squid will include a Via header in requests and
#       replies.
#

However I get VIA header even if "via off".  Why ?

thanks
