There seems to be a problem with the $FullSiteLink feature of the mobile module. When I test this on a mobile device I end up with an endless redirect loop between mydomain.com and m.mydomain.com .
$FullSiteLink in a template creates a link with ?fullSite=1 at the end. The MobileSiteControllerExtension then *should* create a cookie so that for 30 minutes a mobile device would display the actual (non-mobile) site. This doesn't work. The same problem appears with the "full site" link on http://m.demo.silverstripe.com/ .
I tried to print_r($_COOKIE), but it doesn't print any 'fullSite' cookie, neither on a mobile device nor on a desktop browser. Is there not enough time or any other problem with trying to create the cookie just before the redirect?
Any hints would be highly appreciated. For now I will just remove the link but I would love to find a solution for this.
