rails latest stable - Class: ActionDispatch::Http::URL

subdomains(tld_length = @@tld_length)

public

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”.
