It does not validate that it's an HTTP URL, or that the hostname contains .s. Thus, "http://wwwtestcom" is a perfectly valid URL, as is "banana://in.syrup", and anything else that can be parsed as a URL according to the rules in the above RFC. If you need to check for a specific type of URL you'll need to implement your own validation function, or google for one - there's loads out there. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/
