Guys, admittedly, its been a couple of weeks since I cruised by, but I swear that, last time I was here, there was a whole topic on tutorials and other peer-reviewed 'standard' techniques! Was I just delusional then (not unknown to happen) or simply inept now?
I've spent the better part of today preparing a fully-functional (i.e., complete, stand-alone) submission demonstrating how to dynamically create/maintain a MySQL-based, per-guest-session URL 'return' stack. With this facility, the SERVER side can empower a page-based "Back" button (or the like) with the ability to replicate the 'best' functionality of the BROWSER's "Back" arrow. While this may not seem especially useful, it allows the server to [selectively] preserve the state history of the session, thereby overcoming the inherently 'stateless' nature of the net. In my main working site, I use it to detect/squash circular reference loops and simple page 'refreshes', thereby making my server-side return stack considerably more effective than the browser-side stack. Now that I have it, what do I do with it? (Be nice.)
