Every Rails website should implement caching in some form, and I
just finished posting a tutorial covering Page Caching, Action
Caching, Fragment Caching, and even ActiveRecord Query Caching (The
newest Rails caching mechanism only available in RailsEdge).
I wish I could have had a tutorial like this while I was
learning, so I thought I'd post on here. Let me know (offline) if
there is anything you think I can do to improve it.
Part 1 - Introduction & Page Caching
Part 2 - Everything Else
