I solve this problem by redirecting POST to GET.  When data is  
posted, I generate the resulting HTML, save it to a database, and  
immediately redirect to a GET request for the database record I just  
created.  The POST will not show up in the history, and the HTML  
result of the POST request will only expire when I decide to remove  
it from the database.  Much less annoying than breaking the back button.

Peace,
Scott
