Can you tell about your experience working with cookies in a previous project?

In one of my Python projects, I worked with cookies when creating a web application using the Flask framework. Cookies were used to store user session information, such as for authentication and interface personalization.

Example of setting a cookie in Flask:

from flask import Flask, make_response

app = Flask(__name__)

@app.route('/setcookie')
def setcookie():
    resp = make_response("Cookie set")
    resp.set_cookie('username', 'user123')
    return resp

I also handled retrieving cookies from requests to check user status and implemented cookie clearing logic upon logout. It was important to consider security: setting HttpOnly and Secure flags to protect cookies from XSS attacks and transmission over unsecured connections.
