exp_frontedit
cookie, which is created by ExpressionEngine, so users who do not have access to the control panel will always get a fully cached page if it is available.{frontedit_link}
tag in your template for the requested page. Meaning, if you are logged in and have permissions to edit a page, Speedy will not cache anything. It will only cache items on pages when Frontedit is not enabled for the current user.
