Sometimes your web application can be slow. Or you have a surge of traffic. Or you want to run your site on slow hardware or a shared host. For those times you need caching.

Ruby on Rails comes with page, action, and fragment caching built-in. You can use these techniques on single pages or in combinations across the pages of your application.

This screencast show you how to use all three and points out a few troubleshooting tips along the way.

Now with a convenient chapter menu! This is a free update for anyone who purchased this screencast in the past.
