How to identify request from a mobile device
I am making a wcf rest service which will be used from mobile devices. If the request is not from a mobile device, it will not be possible to access the service.

So I need to identify if the request is from android, iphone or windows mobile.

Is there any way that I can identify the request?? I tried to google it but did not get any suitable answer...!!
