I'm using no-cache meta tags on my site and getting great results in IE and FF, but when it comes to Safari, IPad, IPod.etc.. I have problems stopping traffic to the cached page with the back button being clicked. Is this a security issue? I've seen many sites have a way to stop back button activities. I researched the issue online without a happy result. I tried JavaScripting the history.go(-1), too. It only removes the first click on the back button. One more click and you can see the second to the last page. Hmm... Is this a CodeIgniter flaw or a Browser flaw?
