How do you relocate a C.I. app from local host to a webserver?

[eluser]Unknown[/eluser]
What needs to change for a C.I. app to work properly on a webserver?
My current config for the app is for my local host. I need it to work on something like www.servernamehere.com/app


I know the default $application_folder in the "index.php" is just "application", but I'm not sure how to set it to recognize the application when it is moved to a different web server.

How would you configure this?

Thanks!!
