">- if something is wrong I would redisplay the whole form with the

button."

That sounds logical, doesn't it? My main app works this way. You get
your form, fill stuff out and submit. The page returns to the browser
with red error texts above each 'errored' control. Its a work of art.
You can submit repeatedly until all errors disappear. I'm proud.

But click back anywhere during this process, even after 5 submits, the
page is returned blank. Come on, you know SOMEbody is going to click
the back button and call me up, pissed.

So I tried your time example as suggested below:

- Load form. Time is: 2:53:12
- Enter text, submit
- Time is 2:53:33
- Click "Back"
- Time is: 2:53:12

I assume the page is coming from IE's cache cause the time is the same
when going back. If it came from the server the time would be past
2:53:33, right?

So this means... asp.net pages are not capable of maintaining state?
:)

Or that IE is somehow killing the page state when it reloads the page
from its cache?

Nothing is making any sense.

(thx for the reply!)
