强制使用WAP进行Http请求

i readed a lot about deciding if the client uses WAP or not to deliver the right website. But what I want to do is to force the Client to send the Http Request via WAP if its possible to use WAP. I dont know how to do it, but I know that its possible. Does anyone know, how to force a mobile client to use WAP when it connects normaly to the server, or how to create a link to a WAP connection to some server ? Thanks for every answer, I'm googleing since a few hours now and I've really found nothing like this :c

PS:I'm talking about the Wireless Application Protocol just so you dont understand me wrong.
