Hello all,

I’ve been struggling with this for quite awhile and haven’t been able to  
find a solution. I need a user to be able to view multiple top level  
domains with a single login.

My understanding is that this needs to be set in environment.rb and  
called with before\_dispatch. This is what I’ve come up with:

require ‘activesupport’  
require ‘dispatcher’  
module ActionController  
class Dispatcher

```
  def set_session_domain
    ActionController::Base.session_options.update :session_domain =>

```

“#{@request.host}”  
end

```
  before_dispatch :set_session_domain
end

```

end

* * *

However, this does not seem to be working when I try and pull the values  
from session[:session\_domain].

Any help is greatly appreciated.
