Compare with:

subdomain(tld_length = @@tld_length)

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”.

Parameters

tld_length opt = @@tld_length
