v1.0.0 - Show latest stable - 4 notes - Class: ActionController::Caching::Fragments

expire_fragment(name, options = nil) public

Name can take one of three forms:

String: This would normally take the form of a path like "pages/45/notes"
Hash: Is treated as an implicit call to url_for, like { :controller => "pages", :action => "notes", :id => 45 }
Regexp: Will destroy all the matched fragments, example: %r{pages/\d*/notes}
