Hi,
There are ways to validate url

1. validate using reg ex

/(^$)|(^(http|https):\/\/[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}(([0-9]{1,5})?\/.*)?$)/ix

2. Ping the url using 'net/http'

Why not use the standard library?

require 'uri'

begin
  uri = URI.parse(url_string)
rescue URI::InvalidURIError
  puts "Bad URL: #{url_string}"
end
