ZPH in Action 🙂

ZPH is a squid patch that enables SQUID to mark cached packets , so that it can later used by the Mikrotik or squid itself to bypass cached contents from Speed Package.

Z.P.H directives config which works with SQUID 2.7 doesn’t work with new version of SQUID i.e 3.x

Use the following directives in /etc/squid3/squid.conf

# ZPH for Squid3 / zaib
qos_flows local-hit=0x30

then reload squid config by

squid -k rec

Now at Mikrotik, use following rules …

If you have hotspot, then dynamic queue always get on top, so you ahve to apply this line in hotspot user profile, so that every time hotspot user login, zph queue should move on top.
