Parent/Subling ZPH TOS marking

Changelog for ZPH TOS patch of 27-Apr-2004

Removed zph_tos option. Now TOS setting is more precise (read on)

Added a zph_tos_local option for marking locally served hit packets

Added zph_tos_parent allow marking of parent hits as well as siblings'

All integer values (TOS values) can now be also written in hex

Details

You can now use different TOS values for cache HITs produced locally and those by siblings and parent caches.
This is the final set of available options:

zph_tos_local (integer)	Allows you to select a TOS/Diffserv value to mark local hits. Default: 0 (disabled)
zph_tos_peer (integer)	Allows you to select a TOS/Diffserv value to mark peer hits (siblings and parent). Default: 0 (disabled)
zph_tos_parent (on\|off)	Set this to off if you want only sibling hits to be marked. If set to on (default), parent hits are being marked too. Default: on

Please, take a look at SQUID's tcp_outgoing_tos parameter for details about valid TOS values.
