My coworker ran into an issue where NO cookie could be set on Chrome via code like this:
document.cookie = \"TEST=1; expires=Tue, 14 Oct 2014 20:23:32 GMT; pat
The expiry date set for the cookie might be the problem. I have come into a problem like this before on Chrome. Set the date to present or future date and test if it would work. Probably that was how Chrome was designed.
