The cache digest is a cache-to-cache metadata transfer. I'm posing
a more general question: Do we want/need/have to define a cache
system-to-cache system metadata exchange, e.g. interop between
SkyCache, Inktomi, and Squid? Can Squid send referrals to a mirror
system pointed to by Keith's "super DNS oracle"?
- Awareness of other caching systems
- Application level routing of user's requests between caching
systems
- Metadata exchange
Opinions? Flames? Comments?
