Deleting Cookies of non F5 type upon login

I am looking to use the F5 to delete a cookie from both IE and Firefox browsers to eliminate a persistant cookie given by another product within our system. If the user doesnt properly log out and clicks the "X" off our page the cookie doesn't go away unless all browsers are closed. Thus the old cookie is present when a different user uses that same computer if the browser isnt completely closed. Can I write a custom irule to delete the old cookie prior to issuing a new one? this is not an F5 cookie?

 

 

Note, I fount this off the Dev cenral site that put me down the road beleiving it might be possible
