1Caching 2======= 3 4When your application runs slow, throw some caches in. Well, at least 5it's the easiest way to speed up things. What does a cache do? Say you 6have a function that takes some time to complete but the results would 7still be good enough if they were 5 minutes old. So then the idea is that 8you actually put the result of that calculation into a cache for some 9time. 10 11Flask itself does not provide caching for you, but `Flask-Caching`_, an 12extension for Flask does. Flask-Caching supports various backends, and it is 13even possible to develop your own caching backend. 14 15 16.. _Flask-Caching: https://flask-caching.readthedocs.io/en/latest/ 17
