Flask: How to remove cookies?

Question

I set cookies with the code suggested in the docs:

from flask import make_response

@app.route(\'/\')
def index():
    resp = make_response(render_template(.         


        

Answer 1

There's no HTTP header for deleting a cookie. Traditionally you just set the cookie to a dummy value with an expiration date in the past, so it immediately expires.

resp.set_cookie('sessionID', '', expires=0)

This will set the session id cookie to an empty string that expires at unixtime 0, which is almost certainly in the past.
