My Sitecore site has a rule to determine if the mobile version of the web site should be shown. Can anyone explain to me in detail what exactly is happening with this rule? Is there a DLL involved? Is this something that comes with Sitecore out of the box? Is this using 51Degrees somehow?
I found this DLL reference:
EDIT:
The Screen Width Rule Element for Device Detection points to:
Sitecore.SharedSource.MobileDeviceDetector.Rules.Conditions.ScreenWidthCondition, Sitecore.SharedSource.MobileDeviceDetector
/sitecore/system/Settings/Rules/Definitions/Elements/
node. Their items will show you what code is used by them.
