Cancelling a postback event at the master pagelevel...

[Stu]

Hi,

I am writing a script which needs to detect and block if the user has
pressed the Refresh button on the browser.

I have some code on the masterpage that sets up a hidden field counter and
uses a session to keep track of the last value used - if it is the same it
is a refresh - this is detecting fine.

The problem - Now I am detecting the refresh I need to stop the child page
from processing the request. Is there any way to do this globally on the
master page without having to alter 100's of pages individually?

Thanks in advance,

Stu
