Express Detection v4 uses our new, more comprehensive, detection engine. This features staged detection system which means we can detect iPhones, detect iPads and any devices that use the same HTTP headers for a family of devices.
There are a few differences between v3 and v4 which apply to all scripts directly accessing the HandsetDetection object. If you're using our rule builder for redirects then you can safely ignore this article :)
The three main differences are :
1) The calling URL is different
v3 Uses :
v4 Uses :
Where XXXXX is your site id.
2) In v3 the main object was called HandsetDetection, in v4 this object has been renamed to hdRequestObject.
Other minor differences are
- We've added ppi, aliases and displaysize as object properties.
Express v3 will continue to be supported - we have no plans to retire it.
