I've got a regex for detecting links that works pretty well for urls of the form http://example.com, http://www.example.com etc but not for www.example.com

I am trying to extend what i have so that www.foo.com also gets matched without breaking previous functionality.

I tried this:

/\(?\b((http|https|ftp):\/\/|)(www\.)[-A-Za-z0-9+&@#\/%?=~_()|!:,.;]*[-A-Za-z0-9+&@#\/%=~_()|]/

but this only works when www is present and doesn't work e.g. for http://example.com ...
