Video Demonstration (ps: 一个视频教程的介绍)
The following video briefly shows how you can use auth_generator to protect your rails website. Within less than 20 minutes, you'll have your website with articles, but protected to specifics users. You will see how to use caches_page to have a static website to avoid the slashdot effect, but still display account information. The video has been done with version 1.0.0 (things look better now :), since then methods have been renamed, see the FAQ if you need.
