I am thinking of not using a separate admin portal, but instead letting the admin of my application use the same interface as the end users see. The admin will then be able to see special "edit", "delete" links next to blog posts, which users won't see.
But as I understand it, that would mess up caching. If I for example cache the front page of my blog, users could end up being served the admin page instead, or the admin could get the cached standard page instead. Is there a way to switch off caching logic for a specific condition, like a user being the admin?
