#25032 closed Cleanup/optimization (fixed)

When /admin/login/ is accessed directly, there is 302 /admin/login/ after POST, and only then 302 /admin/

While investigating the behaviour for in more detail, I've noticed that when I access (unauthenticated, via GET) /admin/login/ directly, the access_log shows

GET /admin/login/ HTTP/1.1" 200 1716
POST /admin/login/ HTTP/1.1" 302 - 
GET /admin/login/ HTTP/1.1" 302 - 
GET /admin/ HTTP/1.1" 200 2826

The result of the form submission (the POST) is redirect to /admin/login/ again. It seems to be caused by

        if (REDIRECT_FIELD_NAME not in request.GET and
                REDIRECT_FIELD_NAME not in request.POST):
            context[REDIRECT_FIELD_NAME] = request.get_full_path()

When REDIRECT_FIELD_NAME is missing, why is the redirect going to /admin/login/ again? Wouldn't /admin/ be a better target?

Of course, the

        if request.method == 'GET' and self.has_permission(request):
            # Already logged-in, redirect to admin index
            index_path = reverse('admin:index',
            return HttpResponseRedirect(index_path)

will eventually throw it back to /admin/.

This might seem like nitpicking but figuring out correct intended behaviour seems essential when I'm attempting to make changes to it to better support external authentication.

Filed to use the same default redirect target as the authenticated GET access.
