Hiyas,

hi all, I have 10 squids running and I need that one specific object has the same age in all caches.
will ICP solve my problem ? What can I do to solve?
Not directly, but yes (as it will be just part of the solution).
If you configure some kind of hierarchy on your cache servers (sibling,
for example), squid will use ICP to verify if any of its siblings have
the requested object. If positive, it will request the object from the
sibling, and store the object on its own cache.
As a result, all servers will either contain the same cached object
(including http headers), or no object at all. Cacheability rules for
this object will be the same to all servers at the same time.
thanks
