You can certainly start multiple web processes in the same app, but they will be _the_same_app_ (not distinct rack apps). Unless you have some mechanism to track each process (port) then they won't be able to communicate directly to each other. You really want to pass messages off to a bus (e.g. rabbit) and have worker processes handle tasks accordingly. > + can I use a heroku messaging add-on (rabbitmq) to pass messages > securely between multiple heroku apps? Definitely. You'll just need to manually set the addon's config var(s) for each additional app. Jason -- You received this message because you are subscribed to the Google Groups "Heroku" group.
