 * What you need to do is a little bit more complicated than that. You have to check
   the User-Agent string of a browser and match that.
 * More information about User-Agent string: [http://en.wikipedia.org/wiki/User_agent](http://en.wikipedia.org/wiki/User_agent)
 * There are many scripts available out there to help you retreive a User-Agent 
   string. Then use it’s output.

 * Actually believe that it’s hard to find a good user-agent code, but I will keep
   looking
