You are welcome. From implementing a WAP gateway the server part seem to 
work as well, although the traffic was not as high as today's requirements.

Interestingly there was also a multiplexing implemented in the layer 
below (Wireless Transaction Protocol working over UDP) and the gateway 
had to translate this to HTTP.

Regards,
Roland
