Prevent 'Back' Button Action Or Clearing Page History

[RebelFox]

If I set up a set of pages to add a record to a database, is there a way of preventing a session using the 'back' button to then skip back to the 'add confirm' page and submit another addition with the same page values?

This was posted here a while back:

<META HTTP-EQUIV=&quot;Expires&quot; CONTENT=&quot;0&quot;>
<META HTTP-EQUIV=&quot;Cache-Control&quot; CONTENT=&quot;no-cache, must-revalidate&quot;>
<META HTTP-EQUIV=&quot;Pragma&quot; CONTENT=&quot;no-cache&quot;>

This doesn't seem to work for me.
I have coded the html in a set of pages but when I step back
to a page built from an asp read to a database I still see
the same recordset, even though a record has been deleted.

Is there a way of putting up a message 'Page Expired' instead of the same data? I think Amazon do this somehow.

You could put a small bit of code, I don't know what the syntax is in Asp but the idea could be: if refereer is &quot;submitted page&quot; print &quot;Page expired&quot;
