Refresh help

Hi,

I have a cgicc application and the user submits a POST request which does a  
write to a database and on successful completion a status page is displayed. 
If  a user now clicks on the Refresh button on their browser they get the 
following  message - The page cannot be refreshed without resending the 
information. Click  Retry. If they do the information is resent and a duplicate 
now appears in the  database. Is there any around this to avoid creating 
duplicates? To make the status page appear that it was obtained by a GET 
request, for example? So that Refresh requests will only redisplay that
page. Because users do need to refresh the status page.

TIA
Quintin
