What’s the best way to think about redirects for API calls? e.g. You post to create an object, what should you get in return?
The crowd: Some concensus emerged around: send back a 201 with a location header pointing to the url for the object and a body containing the object itself.
Mongoid’s atomic operations don’t trigger hooks (before_save, after_save, etc…)

haproxy, like nginx, can pass http connection through with the header ‘X-Forwarded-For’ set so that it is possible for the app to know the original client IP. But haproxy doesn’t have support for serving as an SSL endpoint, so https:// connections are proxied in tcp mode instead of http mode. And no headers can be added because the request remains encrypted.
Terminate the SSL connection in front of haproxy. PIvots suggested doing this via an additional nginx instance. Online resources show how to do this using stunnel. (http://www.completefusion.com/ssl-load-balancing-with-haproxy-and-stunnel-on-debian/)
Use nginx as the load balancer and discontinue using haproxy, or find a load balancer that fully supports SSL.
