global-variables

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?
