## Talk Description
Caching is something most developers take for granted. Still, time and time again, it’s clear that most developers 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, Harry will cut through the noise, get rid of everything you don’t need, and take you through a series of real-life scenarios to work out how to solve almost any caching situation with a series of questions.

For questions and further discussion find the speaker in the Speaker's Corner right after their talk.
