In case it's of any use I am using #deferred? and TryDefer in my Rails app. I have it set up such that all controller requests are deferred (ie. use threads) apart from those which are, by their nature, asynchronous - eg. I am using Faye mounted at '/ext/bayeux' within my application which already uses the [-1, {}, []] technique to provide an async response. I have #deferred set up by including a module in my Rails::Application instance.
In application.rb:
module App::Application < Rails::Application
require 'extensions/deferred_application'
include Extensions::DeferredApplication
end
In lib/extensions/deferred_application.rb:
module Extensions
module DeferredApplication
BAYEUX_REGEX = %r(^/ext/bayeux(/.*)?$).freeze
def deferred?(env)
!(env['REQUEST_PATH'] =~ BAYEUX_REGEX)
end
end
end
HTH!
Cheers,
Mark.
