Alexa Cookie in Cakebaked (formerly remote2)

How in the world do I keep the cookie so I don't have to reauthenticate on the Amazon site every couple of days?

These are the settings I use

My node was also losing the cookie every few days.
My solution was to include the complete path in the field

My setting has the path
‘/local/alexacookie.txt’
Does it matter if it’s.json or .txt and also what the path is?
