Question about POST

A simple solution around this would be to include another post 
parameter which the user does not enter. It would be automatically sent 
by your standalone. This would work like a password and the CGI would 
check for the correct entry.

Someone would have to sniff the network traffic to obtain the 
"password" to find out what it is -  which is probably unlikely. Since 
it would be embedded in your application and CGI you could make it 
really long and random and therefore virtually impossible to guess. The 
domain restriction could then go away because you have this additional 
level of authentication.
