Method: ActionDispatch::Http::URL#subdomain

Defined in:
actionpack/lib/action_dispatch/http/url.rb

#subdomain(tld_length = @@tld_length) ⇒ Object

Returns all the subdomains as a string, so ‘“dev.www”` would be returned for “dev.www.rubyonrails.org”. You can specify a different tld_length, such as 2 to catch `“www”` instead of `“www.rubyonrails”` in “www.rubyonrails.co.uk”.
