| 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 | |
| extension for Flask does. Flask-Caching supports various backends, and it is | |
| even possible to develop your own caching backend. | |
