Caching
=======

When your application runs slow, throw some caches in.  Well, at least
it's the easiest way to speed up things.  What does a cache do?  Say you
have a function that takes some time to complete but the results would
still be good enough if they were 5 minutes old.  So then the idea is that
you actually put the result of that calculation into a cache for some
time.

Flask itself does not provide caching for you, but `Flask-Caching`_, an
extentions for Flask does. Flask-Caching supports various backends, and it is
even possible to develop your own caching backend.
