Page Expired Message

[sifitz]

Hi,

How do you prevent users from using the browser's back button and re-entering data in a form that has just been posted.

I have often seen the "Page Expired" message and would like to use that.

Is this a web server issue? I am using IIS 5.0

Thanks,

Si

the page expired message is due to the data being read from a database. to my knowledge, there's no way to stop the user from going back per se.
if you're in an intranet environment, you could set a cookie that would verify that the form has already been submitted once and then redirect them on the reload of the page. Actually, you might be able to do that with a hidden field as well.

Thanks for the response. I did a bit more searching because I was hoping that there would be a more simple solution. I have decided to use the javascript history.forward method to redivert the input pages to the page where the details are processed. It appears that due to caching the processing isn't done twice.

Cheers
