Does lift have validation for urls?

Question

I want my users to be able to enter their webpage url when signing up.
Does lift have any built in support for url format validation?

Answer 1

AFAIK, no, but you can create a simple validation rule:

import java.net.{ URL, URISyntaxException };
import scala.util.Try

def isValidUrl(url: String): Boolean = {
  Try { val link = new URL(url); true } getOrElse false
}
