I recently had the pleasure of implementing a custom HTTP web caching layer. While the implementation was fun, I discovered that the caching logic quickly becomes quite complex.
To save you time poring over documentation and RFC’s I created this comprehensive and straightforward guide compiled in a user-friendly PDF cheat sheet for HTTP Caching.

I hope this demystifies some of the HTTP caching strategies, techniques, and best practices.
