var www = new Uri("http://www.stackoverflow.com:80/path/sub.aspx?query=11#!/path2?query2=2");
var t = [];
for (var i in www)
{
    t.push(i + " " + www[i]);
}
alert(t.join("\n"));

uri.js

var Uri = function(uri) {
    var parser = uri.match(/^(([^\:\/?#]+)\:)?(\/\/([^\/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?/);

    var port = parser[4].match(/\:(\d+)$/);
    var segments = parser[5].split("/");
    for (var i = 0; i < segments.length - 1; ++i)
    {
        segments[i] = segments[i] + "/";
    }

    this.AbsolutePath = parser[5];
    this.AbsoluteUri = uri;
    this.Authority = parser[4].replace(/\:\d+/, "");
    this.DnsSafeHost = this.Authority;
    this.Fragment = parser[8];
    this.Host = this.Authority;
    this.HostNameType = /^(\d|\.)+$/.test(this.Authority) ? "Ip" : "Dns";
    this.LocalPath = parser[5];
    this.OriginalString = uri;
    this.Port = port ? port[1] : 80;
    this.Query = parser[6];
    this.PathAndQuery = this.AbsolutePath + this.Query;
    this.Scheme = parser[2];
    this.Segments = segments;
    this.IsAbsoluteUri = (new RegExp("^" + this.Scheme + ":")).test(uri);
    this.IsDefaultPort = this.Port == 80;
};
