flask session timeout

To set a timeout for a Flask session, follow these steps:

1. Import the necessary modules:

from datetime import timedelta
from flask import Flask, session

1. Initialize the Flask app:

app = Flask(__name__)

1. Set the session configuration to include a permanent session timeout:

app.permanent_session_lifetime = timedelta(minutes=20)

1. Use the session object to store and retrieve data:

@app.route('/')
def index():
    session['username'] = 'example_user'
    return 'Session username set'

@app.route('/get')
def get():
    return 'Session username: ' + session.get('username', 'Guest')

1. Run the Flask app:

if __name__ == '__main__':
    app.run(debug=True)
