If some of your pages rarely change, it is wise to activate caching on them. To do so is very easy in Rails. Simply add the following snippet in the appropriate controller:
class PostsController < ApplicationController caches_page :index def index # do something end end
If your controller has some sort of
before_filter to control the access the the resource, use
caches_action instead. Then your callbacks will be run (e.g. `beforefilter :authenticateuser!).
posts.html will be created the first time the page is visited, stored in
/public and served on every new request on the resource.
URL parameters (e.g.
/posts?page=2) are not used to generated the cached page. Make sure you include the parameters you want to use for caching in the path itself:
To expire a cached page, simple do
expire_action :action => :index
