Phonegap build – Open external page in InAppBrowser or childbrowser with no toolbar and close it?

OK, problem 1 to close is solved.
This is what I use to open an external page in the InAppBrowser.
From the page that I load in the InAppBrowser, I can close the InAppBrowser itself, returning to my app from where I opened the browser.

Create a page on your server – closeInAppBrowser.html that is just an empty html page, it doesn´t do anything

I open the browser with this:

<a href="#" onclick="openInAppBrowserBlank('http://www.mypage.asp?userId=1');">open InAppBrowser</a>

var ref = null;
function openInAppBrowserBlank(url)
{
    try {
ref = window.open(encodeURI(url),'_blank','location=no'); //encode is needed if you want to send a variable with your link if not you can use ref = window.open(url,'_blank','location=no');
         ref.addEventListener('loadstop', LoadStop);
         ref.addEventListener('exit', Close);
    }
    catch (err)    
    {
        alert(err);
    }
}
function LoadStop(event) {
         if(event.url == "http://www.mypage.com/closeInAppBrowser.html"){
            // alert("fun load stop runs");
             ref.close();
         }    
    }
function Close(event) {
         ref.removeEventListener('loadstop', LoadStop);
         ref.removeEventListener('exit', Close);
    } 

And to close the InAppBrowser from the page that I opened in the browser(http://www.mypage.asp) I have a button-link like this.

<a href="http://www.mypage.com/closeInAppBrowser.html"></a>

I hope it helps somebody else!
