Caching and Rails

In the big world of webpage serving, Rails and Ruby is a bit slow, but it's good, wholesome, and comfortable! We like Ruby on Rails at 3months.

Caching is a technique for doing work once, and reusing that work later instead of doing it again.

The trickiest part of caching is knowing when the cached thing has changed, i.e when to expire the cache.

You can cache at many levels, client...server...web-server...database. This is mostly about the web-server/Rails level.
