self.csrf_token = self.request.cookies.get('c')
if not self.csrf_token:
    self.csrf_token = str(uuid4())[:8]
self.set_cookie('c', self.csrf_token)
if self.request.method == 'POST' and self.csrf_protect and self.csrf_token != self.request.get(
    '_csrf_token'):
    raise CsrfException('Missing or invalid CSRF token.')
Is there any available solution to provide xsrf/csrf support for Google app engine?
