url: 'https://hnestmann-inside-eu01-dw.demandware.net/on/demandware.store/Sites-RefArch-Site/en_US/CookieCheck-Set'
});
win.add(webView);
 
var webView2 = Ti.UI.createWebView({
top: 250,
height: 200
});
win.add(webView);
 
webView.addEventListener('load', function(e){
webView2.url = 'https://hnestmann-inside-eu01-dw.demandware.net/on/demandware.store/Sites-RefArch-Site/en_US/CookieCheck-Check'
webView2.reload();
});
