Handling page expiry

[Guest]

Hi,

  Would like to know how to set up a page expiry in coldfusion 11.

  Scenario is once a customer placed an order on a shopping cart and order

  completion page is shown and if the user tries to refresh the completion screen,  he should be shown a message saying page expired/order details sent to the mail.

It would be helpful if you can give your suggestion regarding how to handle the page expiry.

Have you tried the obvious page-expiry solution, namely the HTML meta tag,

<META HTTP-EQUIV="EXPIRES" CONTENT="-1">
