Cache Rules Everything | Harry Roberts | performance.now() 2023

Caching is something most developers take for granted, but experience tells me time and time again that most developers also don’t understand how to configure their caching rules safely, correctly, or effectively. Do you know what no-cache means? Do you know what the Pragma header does? Do you know the difference between Last-Modified or ETag? Expires or Cache-Control? You will soon.

In this talk, we’ll remove the noise, get rid of everything we don’t need, and then step through a series of real-life scenarios to work out how to solve almost any caching situation with a series of questions.
