Thanks to the folks who sent their input. The problem turned out to be
because of caching by the local browser. The parameters I was sending
to the CGI were the same from one time to the next and the browser was
returning the output HTML from cache instead of running the CGI. It was
simply matter of sending a date along as an additional unused parameter
that forced the browser to run the CGI each time since each URL is now
unique. *sigh*
