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.
