Now if the token is revoked, we have to remove the token from the data base and then invalidate the cache in all the nodes. Problem is that even a short term load spike lead to system level reset and repair.

When I invalidate the cache, distributed cache has to know what nodes have the entry ( or send a message to all the nodes).

However, Flask-Login makes it nearly transparent - just pass call.

A cookie will be saved on the user’s computer, and then Flask-Login will automatically restore the user ID from that cookie if it is not in the session.

A lot of people mistakenly try to compare "cookies vs. This comparison makes no sense at all, and it's comparing apples to oranges - cookies are a vs. Local Storage" as well where it makes sense to do so.

We setup the servers and put a load balancer (F5, HA Proxy, mod_proxy, Nginx) to distribute the load. We need to handle security, sessions, throttling, and artifact deployments across the servers in the clusters. It is too expensive to hit the database for token per each call, hence we have to cache the tokens. You will tell me that I have to make sure my server is not loaded. This throws “stability” and “graceful degradation” down the drain.The local-memory cache backend doesn’t retain data long enough to be a good choice, and it’ll be faster to use file or database sessions directly instead of sending everything through the file or database cache backends.Additionally, the local-memory cache backend is NOT multi-process safe, therefore probably not a good choice for production environments.(If the login view is not set, it will abort with a 401 error.) The name of the log in view can be set as If you have custom requirements for anonymous users (for example, they need to have a permissions field), you can provide a callable (either a class or factory function) that creates anonymous users to the By default, when the user closes their browser the Flask Session is deleted and the user is logged out.“Remember Me” prevents the user from accidentally being logged out when they close their browser.
