Mangle proxy-hits in ROSv6.5 ?

My transparent proxy in ROS is up and running … in ROSv5.x mangle is working and queue tree rule is alowing to download cashed content with full speed.
But in all ROSv6.x this is not working.
Proxy is using dscp=4
Here is old rule :

/ip firewall mangle
add action=mark-packet chain=output comment="CACHE HIT" dscp=4 new-packet-mark=cache-hits passthrough=no

With all ROSv6.x i dont se that packet is growning …
Im try to add in and out interface … without luck.
What is the correct way to mangle proxy hits with ROSv6.5 ?
Or this is maybe some bug in web-proxy?

bump :smiley:
Can somebody test mangling proxy ?
