Page Expired error in IE

I have a form with a dialog list to select the category to display in an embedded view. After selecting a document for viewing if the user tries to use the back button (or history.back(-1) in an action) they get a “Page Expired” error in IE6. After closing the two warnings, the original page will display. Safari and Firefox do not have this problem. I found a few posts suggesting the @SetHTTPHeader function can solve this, but the Designer documentation only shows how to set a cookie.

Is there any way that I can navigate back to the original form without generating the “expired page” error?

Thanks!

This did it - a computed for display hidden field;@SetHTTPHeader(“Cache-Control”; “private, max-age=10800, pre-check=10800”)

Since the form in question is never saved I don’t have to worry about duplicates being submitted.

This is not a good solution for forms which are submitted.
