From the documentation:

You cannot directly delete a cookie on a user's computer. However, you can direct the user's browser to delete the cookie by setting the cookie's expiration date to a past date. The next time a user makes a request to a page within the domain or path that set the cookie, the browser will determine that the cookie has expired and remove it.

So, your strategy is the right one, and the cookie should disappear from the browser once the response is received.

I'm not sure you can delete the cookie since you don't have access to delete anything on the client computer. All you can do is basically what you are doing, that is invalidating the cookie for your application. I think it is up to the client software to decide if the cookie should be deleted or not, all you can do is set the timestamp as you are doing and that means that you will no longer accept that cookie.
