Dears ...

we have 2 squid caches one for every port 80 connections except videos and the 2nd one for videos only

we can redirect all port 80 connections (with videos) to 1st cache with no problem

but how can we split the videos and redirect it to 2nd cache ?

we try several rules in NAT but with no success...

any idea to solve it ?

I have only one Squid Cache Server on my network . I have solved to split youtube videos with mikrotik , but not other video sites and is working perfectly.

can you help with a squid setup

How??

Maybe with layer7 route marking can split video stream if video streaming had layer7 regex

First Create Layer 7 Rule Name : youtube.com Regexp : youtube.com then im posting my Mangle rules
;;; Youtube Connection Mark
chain=prerouting action=mark-connection new-connection-mark=youtube.com
passthrough=yes protocol=tcp layer7-protocol=youtube.com

;;; Youtube Packets mark
chain=postrouting action=mark-packet new-packet-mark=youtube.com
passthrough=no protocol=tcp connection-mark=youtube.com

;;; Youtube Address List
chain=prerouting action=add-dst-to-address-list protocol=tcp
address-list=youtube.com address-list-timeout=0s
layer7-protocol=youtube.com dst-port=80

Now we have catched Youtube.com Packets

Dears...

we know how to catch all streaming (youtube,mp4,avi,mpeg,mov...etc) by layer 7

but how can we separate this streaming from port 80 connections and redirect it to video cache server ?

I have maded this possible with two RB450G , two PPPoE Lines & one Squid Cache.
Its a complex of configurations that i dont know where to start .
;;; Youtube Connection Mark
chain=prerouting action=mark-connection new-connection-mark=youtube.com
passthrough=yes protocol=tcp layer7-protocol=youtube.com

;;; Youtube Packets mark
chain=postrouting action=mark-packet new-packet-mark=youtube.com
passthrough=no protocol=tcp connection-mark=youtube.com

;;; Youtube Address List
chain=prerouting action=add-dst-to-address-list protocol=tcp
address-list=youtube.com address-list-timeout=0s
layer7-protocol=youtube.com dst-port=80

;;; Youtube Route
chain=prerouting action=mark-routing new-routing-mark=Youtube
passthrough=yes dst-address-list=youtube.com

;;; YouTube Squid Port
chain=dstnat action=dst-nat to-addresses=192.168.7.3 to-ports=8081
protocol=tcp dst-address-list=youtube.com dst-port=80

192.168.7.3 is squid ip adress
I found tha only ROS 6.2 makes this.
but i got one year studying and reading to find the best configs for squid proxy

;;; Youtube Address List
chain=prerouting action=add-dst-to-address-list protocol=tcp
address-list=youtube.com address-list-timeout=0s
layer7-protocol=youtube.com dst-port=80

I think this was our mistake that we didn't work on address list

we will try it and feed back

Instead of youtube.com you must use "googlevideo.com" to handle the videos, at least in my geogr. area.

In case, you do not succeed with your MT-setup, consider to route all traffic to your 1'st squid, and then use special ACLs to forward (youtube.com|googlevideo.com) to 2'nd squid, acting as upstream/parent-squid.

ronix you have running squid servers as i keep getting problems after a week or so so removed them have you got a vm setup so i can look at your config
