If the c++ program is sending data to the file handle that is going back
to the browser (normally stdout), then the c++ program _might_ receive an
error when it prints to stdout if the browser is stopped, depending on how
the web server works.
If a web server detected that the file handle to the browser was closed
then I suppose some web servers might signal the cgi. The script and its
children could arrange to be interupted by that.
I would experiment with those two things on the server in question to see
if your program can detect either one.
Both cases depend on the browser closing the socket when you hit the stop
button, which is not something you control.
