Site Specific Cache Key and Cache Location

[pt ancients <pt.ancientorder@xxxxxxxxx>]

In nginx one can define a specific cache key and cache location for an
accelerated site/domain/url. Or rather, a domain in a reverse proxy
configuration.

Is this doable in Squid?  Specifically 2.6.4..

Or is the cache key and cache location pretty much globally defined/applied.


Thanks!
