Maybe. The USB "stick" that had the back up copy is long lost, though the PC it ran is still gathering dust. Hasn't been powered for over 10 years, so I have no idea if the hard disk or any of it will function any more.

The C program was a basic TCP server with a while loop to accept a connection, fork, read the HTTP header line-by-line, slurp the content (Perl equiv: sysread($connection, $buffer, $contentlength)), use strchr(buffer, '\r') to break the content (which was assumed to be "application/x-www-form-urlencoded") into "key=value" pairs and build an array of pointers (the HTTP headers were also included in the array). Then it would execle(awkint, awkint, awkscript, NULL, array).

The AWK script would then access the HTTP and form fields as environment variables, doing url-decode as needed, process the request and generate the response, including the HTTP headers, streaming it out STDOUT.

This wasn't hard, just very tedious. My co-workers dubbed me "The Wizard of AWK".

Then I "discovered" Perl.
