Fixed #16786 -- Minor cleanups in the memcached section of the caching topic...

Memcached

---------

By far the fastest, most efficient type of cache available to Django, Memcached

is an entirely memory-based cache framework originally developed to handle high

loads at LiveJournal.com and subsequently open-sourced by Danga Interactive.

It's used by sites such as Facebook and Wikipedia to reduce database access and

dramatically increase site performance.

Memcached is available for free at http://memcached.org/. It runs as a

daemon and is allotted a specified amount of RAM. All it does is provide a

fast interface for adding, retrieving and deleting arbitrary data in the cache.

All data is stored directly in memory, so there's no overhead of database or

filesystem usage.

After installing Memcached itself, you'll need to install a memcached

binding. There are several python memcached bindings available; the

      and ``Last-Modified`` headers.
