Unless you use "MPE proglets" instead of CGI... In that case you
could code something like attached below, without having to worry
about CGI issues like "Posix pipe to parent httpd" or "multiple
CGI processes share a single web server job context"...
MPE proglets? Well, admittedly a bizarre approach. I simply was
curious, if a small Java Servlet could act as the "web glue". Also
see http://www.editcorp.com/Personal/Lars_Appel/JavaDemo/proglets/
for details and other examples. And feel free to ROTFL ;-)
