WebAddress

public class WebAddress extends Object
{@hide} Web Address Parser This is called WebAddress, rather than URL or URI, because it attempts to parse the stuff that a user will actually type into a browser address widget. Unlike java.net.uri, this parser will not choke on URIs missing schemes. It will only throw a ParseException if the input is really hosed. If given an https scheme but no port, fills in port
