Facebook application - server not responding - facebook

Question

After the FBML problems I switched to iFrame apps. All well for now except that 2 things:
1) if I did not entered in the app for a few hours and I try to enter, sometimes it gives me the error page that my server did not responded. It shows the Faceboob page with iFrame inside showing the error. After 1 or 2 refreshes it's working fine.
2) I implemented the new SDK with login like this
$facebook = new Facebook(array(
'appId' => $fbID,
'secret' => $fbSecret,
'cookie' => true,
));
$user = $facebook->getUser();
$loginUrl = $facebook->getLoginUrl();
if ($user) {
try {
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
d($e);
$user = null;
}
}
if (!$user) {
echo "<script type='text/javascript'>
top.location.href = '$loginUrl';
</script>";
exit;
}
The problem is my first redirect, when user enters for the first time. It redirects to my server URL not my Facebook app URL. If I try to put it like this:
$loginUrl = $facebook->getLoginUrl(
array(
'redirect_uri' => 'http://apps.facebook.com/xxx/'
)
);
the login is entering in an infinite loop.
Any help solving this two problems is welcome:-)
Thanks

Darko4spain when the user is redirected back to your site, you can detect if is in iframe with javascript and send them back. I have same issue with my app. This is not a pretty fix but it works.
if (window!=window.top) {
//FB.Canvas.setAutoResize();
setTimeout("FB.Canvas.setAutoGrow()", 1400);
}else {
top.location.href = 'https://apps.facebook.com/AnotherFeed/?ref=redirect#comments';
}
example: https://anotherfeed.com/plugins/index.php will redirect you back to my canvas if you are not in the canvas.
