A simple way of handling this is to issue an external redirect once the new data has been successfully saved on POST. This will force the browser to GET the page again, and it will be safe to use the 'Reload' button.

In other words, the user POSTs some new data, you save the data, then send a 'Location: ' header that GETs the same page again instead of redisplaying the page as part of the POST request. This way the browser will always display the page with a GET request.

It means an extra trip back to the browser, but it will solve your problem. The user may have some dificulty if they start playing with the Back button though...
