It’s a browser caching issue, so you need to tell the browser not to
cache.

Several solutions in the before mentioned post were suggested. I used:

before_filter :set_cache_buster

def set_cache_buster
response.headers[“Cache-Control”] = “no-cache, no-store, max-
age=0, must-revalidate”
response.headers[“Pragma”] = “no-cache”
response.headers[“Expires”] = “Fri, 01 Jan 1990 00:00:00 GMT”
end

I’m using Devise for authentication. All works like a charm.

It’s not “my code” - it’s sample code from the Internet.
Your error is now in your code - probably in the handling of
controller actions when users are not logged in.
