Is there a way to test a postback from refresh and back button+resubmit? thanks!

This troubles me for a while. When user click back button and click submit
button, I get the same data as user click refresh(it resubmit the page too).
Is there a way to tell the difference?

thanks.

In SQL Server I use a stored procedure with an output param, and return the
PK from the record to the webform, populating a textbox. If the textbox
contains an value then I bypass the code to add the data.
