Question

I want to track where new users are coming from whenever my app creates a new user record.

I’m grabbing – request.env[“HTTP_REFERER”] which providers a url like:

http://twitter.com/

How can I take any URL and obtain just the domain?

Answer 1

> require 'uri'
=> true 
> uri = URI.parse "http://twitter.com/"
=> #<URI::HTTP:0x00000100994f98 URL:http://twitter.com/> 
> uri.host
=> "twitter.com"
