#25644 closed Bug (fixed)

Setting a cookie after deletion should not keep 1970 as expiry date

Description

If I delete a cookie, and then set it again, the cookie's expiration date will be Thu, 01-Jan-1970 00:00:00 GMT meaning that it is still slated for deletion.

A failing test I wrote to verify this.

This seems easy to fix

  • django/http/response.py 

    --git a/django/http/response.py b/django/http/response.py
index ed5c14e..cdc098f 100644
    a b class HttpResponseBase(six.Iterator):  
    216216
    217217    def delete_cookie(self, key, path='/', domain=None):
    218218        self.set_cookie(key, max_age=0, path=path, domain=domain,
    219                         expires='Thu, 01-Jan-1970 00:00:00 GMT')
     219                        expires='')

Will that still result in the browser deleting the cookie?

Tested, it doesn't.

In 0a19f8d:

Fixed #25644 -- Fixed reset cookie expiry date bug.

Setting a cookie with the same name as a previously deleted cookie
would set its expiry date to 'Thu, 01-Jan-1970 00:00:00 GMT'.
