Python Flask example

In order to store data across multiple requests, Flask utilizes cryptographically-signed cookies (stored on the web browser) to store the data for a session . This cookie is sent with each request to the Flask app on the server-side where it’s decoded.

Unlike cookies, Session (session) data is stored on the server. The session is the interval at which the client logs on to the server and logs out the server . The data that is required to be saved in the session is stored in a temporary directory on the server.

Many times I hear people say that user sessions in Flask are encrypted, so it is safe to write private information in them. Sadly, this is a misconception that can have catastrophic consequences for your applications and, most importantly, for your users .

Default session lifetime is 31 days , user need to specify the login refresh view in case of timeout. Above line will force user to re-login every 5 minutes.

Flask-Session is an extension for Flask that support Server-side Session to your application . The Session is the time between the client logs in to the server and logs out of the server. The data that is required to be saved in the Session is stored in a temporary directory on the server.16 Şub 2021
