Flask session and multiple users

Question

@app.route('/login', methods = ['GET', 'POST'])
def login():
   if request.method == 'POST':
      session['username'] = request.form['username']
      return redirect(url_for('index'))
   return '''

This is the "template" for a flask session login. My question is,

'username'

is mapped to only one value which is the request.form['username']

So what if I have two users login,

(1) 'jack' 

So now session['username'] = jack

And then

(2) 'davis'

So now session['username'] = davis

But then jack is not logged in anymore. How do I do this?

Answer 1

It works. Just test the users (sessions) with at least one user opened in an incognito browser window.
