I need my client side to send a packet (message) to a known ip address. However the target is not aware of it or its purpose.

The packet contains three variables. Thus I say packet as it is very small.

The packet will be noted by a network sniffer (TCPdump, snoop, or whatever). Thus it just needs to travel over the wire in the most readable form possible.

Can anyone give any guidance on the approach? Once sent it has no further value so I do not want to wait for a reply.

The same page may send up to 100 of these without a refresh so I don't want any build up of any resources.

Hope that makes sense. Cheers Nigel
