I use this on asp pages, you will have to modify for zope syntax, but it works very well for your need: Response.buffer = true Response.Expires = -1 Response.AddHeader "Pragma", "no-cache" Response.AddHeader "cache-control", "no-store" ------------ Original Message -----------

All,

Has anyone figured out a way to prevent a user from going "Back" to a page once they have passed it.

The situation:

We have an Order Entry/Billing intranet site where users fill out several pages of data an then submit the information. After the order is submitted we would like to prevent them from backing up and resubmitting the same order. Is there a way to prevent them from doing this.

I know I can remove the tool bar, but then the user can right click and select "Back" or select GO|Back.

Any Ideas?

DR
