Hi,

I'm new to AT= S, so far we've been using Squid, but due to it's instability are m= oving away.

I'm interested in avoiding regiona= l cache duplication in CDN system. Currently, we have several Squid servers= working as siblings and only pulling from origin if none of them has the o= bject in cache, if sibling has object in cache, it's pulled from siblin= g but not stored locally. Only new content fetched from origin is store loc= ally. Sibling lookup is done via ICP and has been working quite well so far= .

Is similar setup possible with ATS?
I = found no information in documentation how to configure siblings (only paren= t configuration is documented). Could you point me to right direction?

Regards,
Veiko
