How do I detect whether or not code is being run from a rails server?

Question

Hi all,

I have a rails app and I run the main rails app on a mongrel server. However, I also have an comet server (using EventMachine) running using the rails environment (so it can access the database). However, Mongrel seems to mess up EventMachine. My question is, how can I detect whether or not I am running the rails environment from the rails server or from the EventMachine server so I can require the mongrel gem only in that case.

Thanks.

Answer 1

request.server_software()

Answer 2

I figured out what to do. I already have some global variables declared for the EventMachine server, so I check to see whether or not they're defined. If they are not, then I know it's not running the EventMachine server.
