This piping not needed anymore, it has been fixed
after indexer example was addded.

Regarding your script: I must admit I am not a CGI expert,
but maybe you need to echo "HTTP/1.0 200 OK\r\n" first.

I just tested and cgi indexer works (also without piping thru dd),
so at least this cgi example is working.

If you definitely know that CGI should not print "200 OK"
(IOW: that https server process should add that instead),
please give me the URL so that I can educate myself too.

Thanks.
