django - passing information when redirecting after POST

Question

I have a simple form, that when submitted redirects to a success page.

I want to be able to use the data that was submitted in the previous step, in my success page.

As far as I know, you can't pass POST data when redirecting, so how do you achieve this?

At the moment I'm having to just directly return the success page from the same URL, but this causes the dreaded resubmission of data when refreshed.

Is using request.session the only way to go?
