I know how to retrieve the current :controller and :action, but is there  
a  
variable available for me to retrieve the URL items such as:

[subdomain.mydomain.com](http://subdomain.mydomain.com)

I would like to be able to pull “subdomain” out of the URL. Is this  
possible with something built-in?

Thanks,  
David

You might want to look into acts\_as\_subdomainable 🙂 Just kidding,  
but you might look into this plugin:

It probably has the goods to get you going.

@request.subdomains will give you an array of all the subdomains. In the  
example you gave, @request.subdomains.first would return “subdomain”
