Subject: Environment Variable for Ruby on Rails

Is there an entry in the request.env hash for the host header?  I can
parse the request.env["REQUEST_URI"], but I was just wondering.  I
couldn't find any documentation on the contents of that hash --
http://api.rubyonrails.com/classes/ActionController/Base.html appears
to only show a couple of the keys.

Thanks!
Tom
