-You can define the Builtin Private Actions within your controllers as well. Default actions will override the ones in lower level controllers/global, while begin/end actions will be chained together, so if you have a default action in MyApp::C::Foo::Bar as well as a global one, and a global begin/end, as well as a begin end in MyApp::C::Foo and MyApp::C::Foo::Bar, the components will be called as follows:

 =head4 B<URL Argument Handling>
 
 If you want to pass variable arguments at the end of a URL, you must use regex actions keys with '^' and '$' anchors, and the arguments must be separated with forward slashes (/) in the URL. For example, suppose you want to handle /foo/$bar/$baz, where $bar and $baz may vary:
