Where is your code? What problems are you having with it?

[Ulf Dittmer]

It sounds like you wish to ensure that something like "www.xyz.com" is entered - be aware that web site addresses don't need to start with www, and can have one, two or more dots.

Are you basically asking how JavaScript regular expressions work?
