I have split off the User Authentication of our main application into it’s own application. I would like have this called from the main application. How can I have multiple instances of “script/server” running when there’s only one localhost:3000? I believe I can then simple switch applications by routing. Thanks. ---

you can use ./script/server -p 4000 LaughingNinja wrote: > I have split off the User Authentication of our main application into > it�s own application.

Thanks. That was easy 🙂 On Feb 4, 2:44 pm, Nginx L. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

That would me my long term recommendation.

If you use Mac OS X, you could use Passenger Preference Pane: [http://www.fngtps.com/2008/12/passenger-preference-pane-v1-2](http://www.fngtps.com/2008/12/passenger-preference-pane-v1-2) 2009/2/4 Julian L. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

Thanks for all your input! I’m using the alternate port and it’s working. However, I now have another issue: How can I send the Session: hash to the other application. We have a Calendar application in house where users can sign up for training classes. So, once the User is authorized in the User Authentication app, I’m redirecting to the calendar app. I need the Session: which contains the User object to tie the user to a lesson. What’s your suggestion for passing this between apps? Thanks again. On Feb 5, 7:23 am, Nginx L. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

here are some resources that can get you started [http://en.oreilly.com/railseurope2008/public/schedule/detail/3557](http://en.oreilly.com/railseurope2008/public/schedule/detail/3557) (includes a ppt) > **[GitHub - fcheung/rails\_conf\_demo: Code used in the Intellectual Scalability...](https://github.com/fcheung/rails_conf_demo/tree/master)** > > master although i think for your needs, you could just exploit the RESTful actions design in Rails. For eg, your Calendar app should request authentication by specifying a specific controller action in the Authentication app (using complete URL, As Far As I Know) and your Authentication app should return the Session hash.
