Note that the cookie is not changed every request, just the token retrieved
by the `get_token()` method (used also by the `{% csrf_token %}` tag).
While at it, made token validation strict: Where, before, any length was
accepted and non-ASCII chars were ignored, we now treat anything other than
`[A-Za-z0-9]{64}` as invalid (except for 32-char tokens, which, for
backwards-compatibility, are accepted and replaced by 64-char ones).
Thanks Trac user patrys for reporting, github user adambrenecki
for initial patch, Tim Graham for help, and Curtis Maloney,
Collin Anderson, Florian Apolloner, Markus Holtermann & Jon Dufresne
for reviews.
Added the CSRF_TRUSTED_ORIGINS setting which contains a list of other
domains that are included during the CSRF Referer header verification
for secure (HTTPS) requests.
Only compute the CSRF_COOKIE when it is actually used. This is a
significant speedup for clients not using cookies.
Changed result of the “test_token_node_no_csrf_cookie” test: It gets
a valid CSRF token now which seems like the correct behavior.
Changed auth_tests.test_views.LoginTest.test_login_csrf_rotate to
use get_token() to trigger CSRF cookie inclusion instead of changing
request.META["CSRF_COOKIE_USED"] directly.
