}
maChat.prototype = new maWeb( this.url );

function callback( evt, maweb ) {
    var t = "test";
    var p = t.subStr(2);
    var obj = maweb.getObj( evt );
    var stat = maweb.getStat( evt );
    alert( stat["code"]+stat["text"]+" "+ JSON.stringify( obj ) );
}

function sendmsg( ) {
    var cmd = {};
    cmd["type"] = "cmd";
    cmd["cmd"] = "initdata";
    cmd["me"] = 0;

    try {
        var conn = new maWeb( "http://localhost/mafw/chat.ma" );
        conn.send( JSON.stringify ( cmd ), callback );
    } catch (e ) {
        alert (e);
    }
