How to set global variables to use everywhere in my application?

I am using Ruby on Rails 3 and I would like to set some global variable to use those everywhere in my application. In particular, the domain name.

If, for example, my website URL is

http://subname.domain.com

I would like to set or retrieve the subname.domain.com value in order to use that in my application like this

request_uri = "http://#{sub_domain_name}"

Where and how I have to state\initialize the sub_domain_name variable or other variables at all?

You can add an initialiser in config/initializers/ where you can declare and set the values of global variables / singletons, which would be available to your app.

Application controller is one place where you can set global variable. Just call a before_filter method in the landing function of the application.

If your question is specific to retrieving domain name of your application, you can use request.env['HTTP_HOST'].

Thanks....
