HTTP adapter URL Parameter

HI we are currently integrating a http to rfc connection with the URL in the format of

http://sdn.sap.com?name=Joe&country=India

we want to pass the url parameters name and country to a rfc in sap but we are having difficulties using the apply URL Parameters on the sender http adapter when it comes to message mapping. can you give a sample xml that will be generated when we received the said URL and how we can map these on the receiver RFC. Thank you in advance'
