Django redirect to previous page after external OAuth login

Question

I am using Twitter OAuth to login users. The login takes users to Twitter and upon successful OAuth returns them to a specified url. From this url I would like to redirect users back to the page they were on before logging in.

What is a good way to do this?

Two ways:

1. Craft your OAuth URL so it sends them back to the right page, or at least says next=url in the querystring. This is most reliable but can break (and does look ugly but who's copying and pasting OAuth URLs anyway?)

2. Store a session containing the last requested "real" page. I say "real" like that because I don't count any auth/registration pages as real. So every hit, check to see what URL they're on, if it's not auth-related, store it in session. When they hit your OAuth-auccess page, redirect them to the session value. You can do this in a context processor or some middleware. Requires cookies and logout will nuke it.
