Object Cache support

[swissspidy]

Memcache (or Memcache_d_) and Redis support would be nice via object-cache.php.

I think Simple Cache does this nicely. WP Spider Cache has a nice abstraction, too.

A bit late but i stumbled across this issue. The DB-Cache relies on transients that are cached. AFAIK transients will automatically be cached in memcache(d) or redis.

I made a test on our server: without memcache, transients are generated and viewable in the DB. With memcache enabled, no transients found in the DB but the output is cached (visible in the footer notice).

That's correct, the "DB" backend actually utilizes set_transient() which might end up in DB or an external object cache depending on the system setup.

Explicit memcached (since 2.0.7, 2013) has a slightly different structure, so it can be included directly in the webserver config to skip all WP logic and the same holds for the recently added Redis backend (which will be included in 2.4.0)

Both could be refactored to utilize WP's object cache abstraction and we should probably extend the documentation on the "DB" backend, but neither should have significant impact on the overall functionality.
