Mirroring on the air

I want to create an Airplay server like AirServer . I am following the unofficial AirPlay protocol specification and received a Post / stream request

            {

    }
);
version = "211.3";
}

      

        
        
        
      

    

After this request, the connection dropped, I tried to send an NTP request, but it doesn't work.

So, I want to know what I need to do next or how to send an NTP request?

Thank.
