In my project, I need to send a lot of equal push notifications to a lot of windows phone devices. Is there a way to send a push notification with multiple receivers or do I have to make one http request per device? I've found a lot of good tutorials but no information about this issue.
Good tutorial (has downloadable project with server, wpf application and wp7 app which works immediately): http://www.thisisfanzoo.com/Blog/JeffF/archive/2010/08/02/a-really-long-post-about-the-windows-phone-7-push.aspx
