Method: ActionDispatch::Http::URL#subdomains

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

#subdomains(tld_length = @@tld_length) ⇒ Object

Returns all the subdomains as an array, 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”.
