Comment (by M):
I note that Django's CSRF token output uses single quotes - value='....' -
whilst form outputs by default use double quotes - value="...".
This means it seems impossible by default to cause a request to reflect
something that would match the same prefix. You would have to guess the
first three characters of the token cold (a large number of requests) in
order to get started.
