[LRUG] Rails: Loading A Plugin On Each Request

[Pratik Naik]

Another hack is to probably use a Dispatcher.to_prepare callback and
load ( not require ) your plugin's init.rb. Something like following
in your env.rb:

require 'dispatcher'

Dispatcher.to_prepare do
  load 'vendor/plugins/whatever/init.rb
end

That might do the trick ? Untested.
