Can you tell in ASP if the back button has been pressed?

[Kevin Audleman]

Hello,

Is there a way to determine if a user has navigated to a page by
clicking the back button? I've got a page that dynamically generates a
form and submits it, the problem being that clicking the back button
has the effect of resubmitting the form. I'd like the back button to
work if at all possible.

Thanks,
Kevin

you store a transaction guid in a hidden field. then you store the guid
on the server when posted back. then on a second postback from
browser/firewall/proxy you can detect its happened already.

Thanks Bruce. How do I store a transaction guid on the server?
