/// </summary>
public static uri absolutewebroot
{
    get  www.jb51.net
    {
        var context = httpcontext.current;
        uribuilder uri = new uribuilder();
        uri.host = context.request.url.host;
        if (!context.request.url.isdefaultport)
        {
            uri.port = context.request.url.port;
        }

        uri.path = virtualpathutility.toabsolute("~/");

        uri absolutewebroot = uri.uri;
