Constant Summary

Url =

Regex from www.igvita.com/2006/09/07/validating-url-in-ruby-on-rails/

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

EmailAddress =

Almost RFC2822 (No attribution reference available).

This differs in that it does not allow local domains (test@localhost). 99% of the time you do not want to allow these email addresses in a public web application.
