I could imagine a two level cache backend where I configure a backend 
for first level caching (e.g. TransientMemoryBackend) and second level 
caching (e.g. DatabaseBackend)

When 1st level cache misses, the two level cache backend fetches from 
second level cache and sets first level cache if this hits. If 2nd level 
cache misses, the 2level cache backend returns FALSE and the application 
code can generate the cache entry.

This would perfectly fit into the domain of the caching framework and in 
fact other caching frameworks have implemented this (e.g. ZendCache).

Kind regards,
Helmut
