Hi Raul,

if you dont know the cookie-name you cannot reset them from nginx,
but i see quite a few in my developer-tools.

i'd suggest you create a location that match this false redirect-location
and reset the cookies from within this location, and the redirect
users to / after this reset.

btw, i think it is bad design to place redirect-information into cookies.
