expiring pages

[Gav]

Hi,
I have a form which sibmits data to another page. Trouble is when the user
refreshes the page it resubmits all the data again.

Is there anyway to expire the page immediatly so this cant happen??

The process and redirect model is well suited for this. You can implement it
with or without post-back. Here are a couple of stripped down examples:

Process and redirect with post-back ---------------------------
[p1.asp]
<%
If Request.Form.Count AND (validation criteria) > 0 Then
{ process data, assign cookie or session info }
Response.Redirect("p2.asp")
End If
%>
...
<FORM ACTION="p1.asp">

[p2.asp]
<% { read cookie/session data, process page } %>


Process and redirect without post-back ------------------------
[p1.asp]
<FORM ACTION="p2.asp">

[p2.asp]
<%
If (validation criteria) Then
{ process data, assign cookie or session info }
Response.Redirect("p3.asp")
Else
Response.Redirect("p1.asp")
End If
%>

[p3.asp]
<% { read cookie/session data, process page } %>

Yeah, 3 files

form.asp
formaction.asp (with redirect to...)
formconfirmation.asp

also, then they hit the back button, it will take them back to the
form, instead of formaction
