Yup, it's my opinion, and it's based on some experience. All users aren't idiots, but many are. I have one guy who's terminal & profile need to be reset every couple of weeks because he keeps messing up his password. He's been with the company, using the same terminal and application, for five years. > > If the tube goes, it goes... not much you can do about it.

I don't code for it because it's extremely rare. The same can hardly be said for hitting a back button. > > A book falling on the keyboard will NOT give you Alt-leftarrow.

It's easy to provide with a stateful connection. From what I've read, and I certainly could be wrong (I'm no HTML expert), the only way to emulate this would be to turn off caching at the browser. That has disadvantages of it's own. If you know of a better way, please share it, or provide a URL where I can get a headstart on doing my own homework.
