As of v6.0, ATS does not support Partial object caching (ala byte range 
caching).
However, ATS does support returning partial byte range responses if the whole 
object is already cached. Background Fetch plugin takes advantage of this fact, 
by initiating a full object download in the background on receiving a byte 
range request for an object that's not in the cache yet. Once the full object 
is downloaded and populated into the cache, subsequent byte range requests are 
directly served from the cache.

Thanks,
Sudheer

I have legacy forward proxy used in enterprise network facing to internet 
behind firewall. Unfortunately it cannot do partial object caching. I am 
looking if I can get an alternate proxy to do this. My requirement is: 1.      
Partial object caching so updates by apple etc. can be cached. Also video 
caching will just work. 2.      Streaming to multiple client at same time 
should be possible from single server connection.    It seems varnish can do 
above stuff. But it works effectively as reverse proxy, so I have to position 
it before my proxy, as it cannot work as upstream proxy directly. Also its 
cache seems gets vanished after restart(Everything in cache is from heap). Do 
you guys know if ATS can do this functionality? I believe it is not possible, 
but I thought just ask if we achieve this by any means. A pointing to how to 
would be really appreciated.       Thank you from Newbie, Madhava
