Question

I have a website which is http://www.abrisud.com. This website has 7 domain names (one for each language): abrisud.com, abrisud.it, abrisud.de, etc… and abrisud-enclosure.co.uk.

The problem is on the last one: I am losing my session on every single request. Each Time I load a page I have a different session ID. On the other domains everything is working just fine.

The website is running ruby 1.8.7 and rails 3.0.0.

I am really convinced that the problem comes from the “-” in the domain name but I just can’t find anything (or almost anything) on the subject through the web.

Hopefully I am being clear enough, if not just tell me.

Answer 1

Here is the answer :

From Module ActionDispatch::Http::URL (Rails 3.0.x), be sure to read the comments 😉

# Returns the \domain part of a \host, such as "rubyonrails.org" in "www.rubyonrails.org". 
# You can specify a different <tt>tld_length</tt>, such as 2 to catch rubyonrails.co.uk in "www.rubyonrails.co.uk".
def domain(tld_length = 1)
  return nil unless named_host?(host)

  host.split('.').last(1 + tld_length).join('.')
end
