Remove Google Analytics cookie

We had an wrong script inserted by Google Tag Manager on our page, that caused 403 error. The script was removed and after wiping out the cookies (or just _gs cookie) our page works fine.



The problem is that the users, who entered the page when we had the wrong script still have the _gs cookie, and they still get 403 error.



How can we make their browsers remove that cookie, while our index page is not even reached?



The setup is a Sitecore CMS set up on IIS 10.

          You can try "expiring" the cookie. All that would need to be done is add that cookie back but with the expiration date set to a date/time in the past. That way the cookie would be treated as expired and would pick up the new value if it exists.

          Our application is set up on Azure VM, but the connection is through Application Gateway, which has a firewall. Apparently, the firewall considered the content of the mentioned _gs cookie suspcious, and it was the Application Gateway, that returned 403, and not the IIS itself.



          Adding the _gs cookie to the whitelist solved the problem.
