For the past day, I’ve been tracking down a hair-pulling-ly frustrating bug in Rails ( with Authlogic on Passenger).
My sessions weren’t sticking in production
Cross-domain or otherwise (doubly frustrating because a) Authlogic has been so rock solid for me otherwise, b) worked as expected in development).
Turns out, I wasn’t setting the session domain correctly in environments/production.rb.
config.action_controller.session[:domain] = '.YOURDOMAIN.COM'
Note the dot (it’s there for subdomains). Oh, and be sure to correctly spell your domain name…or sessions won’t work at all.
