[wp-hackers] Caching as part of the core

[Brian Layman]

The way you've phrased the question illustrates how these discussions 
can become confusing.  I'll answer as best I can.

You asked about "an object cache" as opposed to "the object cache".  So 
I'm not sure what you call an object cache.  You would implement 
fragment caching using a "persistent cache" and I think that's what you 
were asking about.

However there may be reasons why you don't care to implement it using 
the WordPress Object cache class WP_Object_Cache. That class has a 
number of features like grouping and cache versions that you may wish to 
avoid for whatever reason.  You may simply prefer using straight PHP 
memcache calls http://php.net/manual/en/book.memcache.php or want the 
data in separate server from the object cache. The why of it depends on 
the project and the programmer, fortunately, you only asked how.
