Subject Re: partial object caching
Date Thu, 06 Aug 2015 15:05:51 GMT
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

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
