web: bundle exec puma -C config/puma.rb -p $PORT
worker: bundle exec sidekiq -e $RAILS_ENV -q default -q mailers

# By default, sidekiq only operates on the `default` queue
# So if you do `Mailer.new(...).deliver_later`, those are queued to the `mailers` queue
# Hence you need to explicitly tell Sidekiq to operate on `mailers` queue too
# You can also put this into sidekiq.yml

# To enable SSL in Rails you could now simply use *force_ssl* in your 
# ApplicationController but there is two more things to think about:
# In development our SSL webserver is running on port 3001 so we would
# actually need to use *force_ssl port: 3001* but then this wouldn't
# work for production.
# Also there is a good chance you might not always want to use SSL in development
# so it would be nice if we could just enable or disable SSL in the config.

# To make all this work first copy the file *ssl_with_configured_port.rb* to
# your *lib* directory. Second to enable SSL add *config.use_ssl = true*
