Upon install of my app on a Facebook Page, I\'d like to send the user to an URL with further instructions. I\'m starting the installation with http://facebook.com/add.php?ap
First page that Canvas is point to should have
< script type='text/javascript'>top.location.href = 'REDIRECT-URL';< /script>
So when your app is opened it will automaticaly redirect to REDIRECT-URL
I'm not sure that you can avoid opening of application canvas page after installing application.
