A small JavaScript file that can clean out accumulated cookies related to Google (Analytics) tags on the *.illinois.edu domain.
The example below sets the threshold to 40 cookies maximum before the script would clear all cookies starting with _ga_. The default is 30 cookies maximum and acts as a lower bound to prevent excessive clearing.
