 In this example the filter is added to +ApplicationController+ and thus all controllers in the application inherit it. This will make everything in the application require the user to be logged in in order to use it.

You can prevent this filter from running before particular actions with +skip_before_filter+:
 
 <ruby>
-class LoginsController < Application

-Verifications make sure certain criteria are met in order for a controller or action to run. They can specify that a certain key (or several keys in the form of an array) is present in the +params+, +session+ or +flash+ hashes or that a certain HTTP method was used or that the request was made using +XMLHTTPRequest+ (Ajax). The default action taken when these criteria are not met is to render a 400 Bad Request response, but you can customize this by specifying a redirect URL or rendering something else and you can also add flash messages and HTTP headers to the response. It is described in the "API documentation":http://api.rubyonrails.org/classes/ActionController/Verification/ClassMethods.html as "essentially a special kind of before_filter".
