Perhaps the Post/Redirect/Get pattern can help you out:

It sounds like you are running in a rails environment and someone more
knowledgeable than me about rails will have to comment on whether this
pattern can be (or already is) implemented by Rails.

The idea is that instead of responding with a page of content to a POST
request, the controller should respond with a Redirect (most likely to
itself).  The redirect will cause the browser to issue a GET back to
the controller and the original POST request will *not* be saved in the
browsers history. If you do a page reload at this point you end up
reissuing the GET and not the original POST.
