Dear Lazy Web,

Can anyone point me to a simple introduction to HTTP caching? I know quite a lot about it and can just dive into the relevant standards, but I’m writing an article that will be read by people who have never heard of HTTP cache control headers before and I’d like to give them a good starting point.

Thanks,

Lazy author, er believer in reuse…

This article on MNot has an excellent overview of the whole issue.
