16785	Document cache design in `misc/design-philosophies`	jamesp	Tim Graham	"I initially found the design of the cache backend classes confusing, especially with respect to references to Memcached in {{{django.core.cache.backends.base.BaseCache.validate_key()}}} .  I found that this was added a year ago in ticket #6447, so I figured there was a good reason but it was not explained anywhere I could find.

I discussed this with a couple core developers and hopefully the attached patch will be suitable."	New feature	closed	Documentation	1.3	Normal	fixed			Accepted	1	0	0	1	0	0
