Keep POST variables while redirecting login to GAE?

in the form, I send the data to the python webapp handler (the entire Google App Engine) using an HTTP POST request. In this script, I first check if the user is logged in, and if not, I use users.create_login_url (...) to redirect the user to the login page first.

How can I make sure that after logging in, the user is not only redirected to my python script again, but the POST variables are also saved? The only way I found is to turn all the POST variables into URL parameters and add them to the URL.

Is this even possible?
