[pokk]

В общем в мазиле хроме работает,а в этом .... ругаеться на строчку
if( http2 ) { , на http2 что ему надо ?

var http2 = createRequestObject();

    function GetSettingTimeout3(link,ModeFuncCall,CallbackTrue,CallbackFalse) {
        (function _f() {
            if( http2 ) {
                http2.open('GET', link, true);
				http2.timeout =1000;
				//---------------------------------------------
                http2.onreadystatechange = function () {
					if (http2.readyState == 4&&http2.status == 200) {
						
					if (CallbackTrue && typeof(CallbackTrue) === "function") {
						CallbackTrue.call(http2.responseText);
					}						
						
						//CallbackTrue.call(http2.responseText);
						//ConnectSuccessful();
						if(ModeFuncCall==CYCLIC){
							TimerID = setTimeout(_f, 1000);
						}
                    }
                };
				//---------------------------------------------
				http2.ontimeout = function() {
					//Disconnect();
					TimerID = setTimeout(_f, 1500);
					if (CallbackFalse && typeof(CallbackFalse) === "function") {
						CallbackFalse.call(http2.responseText);
					}
				}
				//---------------------------------------------
				http2.abort= function() {
					if(StatusAbort==ClearAbbort){
						//Disconnect();
						StatusAbort=ClearAbbort;
						TimerID = setTimeout(_f, 1000);
					}
				}
				//---------------------------------------------
                http2.send(null);
            }else{
