How can I implement session timeout in Flask?

You can implement session timeout in Flask by using the session.permanent attribute and setting a timeout duration.

Can you show me a code example?

Sure! Here's a simple example:

from flask import Flask, session

app = Flask(__name__)
app.secret_key = 'your_secret_key'
app.permanent_session_lifetime = timedelta(minutes=5)

@app.route('/login')
def login():
    session.permanent = True  # Make the session permanent
    session['user'] = 'username'
    return 'Logged in!'

@app.route('/logout')
def logout():
    session.pop('user', None)
    return 'Logged out!'

What happens when the session times out?

When the session times out, the user will be logged out, and any session data will be cleared.
