Craig Forster commented on AIRFLOW-2866:
----------------------------------------
[~TaoFeng] Running locally with that branch seems to fix things. I can toggle
the on/off state for a DAG without the callbacks being rejected for CSRF
errors. This is for a single web server instance only.
I don't believe this will resolve the issue for a cluster of webservers serving
requests in a round-robin fashion, though. Each webserver instance will still
have a different secret key and reject CSRF tokens from other cluster members.
