---------------------------------

hi guys,
i coded in the past a plugin to handle this issue in a per domain fashion

it is called domain_tos plugin and works like the cacheurl plugin, where admin can set 3 parameters at domain_tos.config file:

Example of domain_tos.config:

# Format: [regex for domain] [tos_if_miss] [tos_if_hit]
# desidered tos_if_miss, tos_if_hit should be multiplied by 4 (TOS)
# values equal 0 does not alter the native DSCP field value

# QoS for social networks - DSCP 2(miss) 3(hit) 
http://.*\.facebook\.com 8 12
http://.*\.fbcdn\.net 8 12
http://plus\.google\.com 8 12

# QoS for porn hosts - DSCP 4 (miss) 5(hit) 
http://.*(xvideos|redtube|porn) 18 20

#  QoS for others domains DSCP 0(miss) 1(hit)
http://.* 0 4

> Hi Guys 
> I wonder if it would be possible to have a plugin that we can assign TOS/DSCP bits to the objects that are being a cache HIT or maybe object type of video/audio. 
> such a plugin would give us better performance and control on how to distribute the output of the cache towards clients. 
> example : 
> suppose i set traffic to clients each of different bandwidth. 
> on a router on a link somewhere on some roof top building i can say this client can get miss object traffic of 512Kbit/s and 1Mbit/s of Hits from the cache. 
> this way if this client is getting a cached object he would get it in 1Mbit/s while his non cached requests would be of 512Kbit/s 
> hope whoever does this patch plugin takes into consideration the mime type or url of the object being retrieved maybe i want to set audio/video being cached or not to have 768Kbit/s while windows updates and android/iphone apps should take no more than 512kbit/s 
> bear in mind that this has nothing to do with Origin servers throttling feature request. this is just client side feature set. 
> much regards
