I apologize if this answer doesn't help much -- I'm confused by your question.
request.POST doesn't cache anything. It's simply filled with data submitted by the browser on that specific request. If you click "Back" on your browser, many times the browsers will simply re-fill those form fields in with what you had typed in before. This is nothing specific to Django. I'm not aware of any HTML methods to inhibit this behavior. Keep in mind that it is good practise to have a redirect after every POST. For example, when the user submits the form, process that form, then redirect them to display whatever you want them to see, even if it is just additional form fields (within the same, or another, view). I'm not sure what you're trying to achieve by clicking on the "back" button -- but if you give some more information on what you're actually trying to achieve, I'd be happy to try give you some better help. Good luck!
