title: Tell browser to explicitly not post data to new url after redirect
body: <p>I would like to do a temporary redirect (307) on a page which accepts POST data. The page it is being redirected to does not need that data to be posted to it (the POST data is already processed on the initial landing which does the redirect). </p>
  
  <p>Maybe it's new in Firefox, but it prompts the user with "This web page is being redirected to a new location. Would you like to resend the form data you have typed to the new location?". I would like to avoid that prompt, and explicitly state that the data does not need to be posted to the new URL.</p>
  
  <p>Is there an HTTP header that would specify this?</p>
