[Flask] Flask-Security can’t work with Gunicorn with multiple workers

[Unai Rodriguez]

Hi 王帅,



It seems that somehow your application is storing information that's
only available to the Gunicorn instance that the client connects to.


Have you tested forcing the same user connecting always to the same
Gunicorn instance? That should probably work.


Where are you storing the session information?
