How to parse url to get base url? -- Rails 3.1

How can I parse urls like

http://www.1800contacts.com/productlist.aspx?dl=P&source=cj&ac=8.2.0007

and only get

http://www.1800contacts.com

?

PS. Some urls have subdomains etc so I can't use regexps here.

I like @skojin's answer number 1 (sorry I opened another answer, it's only a long comment) because it makes more general code for both cases:

require 'uri'

uri = URI "http://www.1800contacts.com/productlist.aspx?dl=P&source=cj&ac=8.2.0007"
uri.query = uri.fragment = nil
uri.path = ""
uri.to_s
# => "http://www.1800contacts.com"

uri = URI "http://example.com:8080/you-found-me.php"
uri.query = uri.fragment = nil
uri.path = ""
uri.to_s
# => "http://example.com:8080"

2 alternative ways 

uri = URI.parse(url); uri.path = ''; uri.query = nil; uri.to_s
url.split('/')[0,3].join('/')

Try to use 'uri' library:

require 'uri'
address = 'http://www.1800contacts.com/productlist.aspx?dl=P&source=cj&ac=8.2.0007'
uri = URI.parse(address)
puts "#{uri.scheme}://#{uri.host}"  # => http://www.1800contacts.com
