Hi Folks

After many hours of trying different things to cure the above problem, I suddenly wondered about CGIWrap and did a search for it on this forum. The server is a Sun Cobalt RaQ. The scripts are passed through CGIWrap.

Apparently there is a peculiarity of the Cobalt RaQs which prevents the correct transmission of value pairs when the script is called using the POST method.

So to fix:
The definition of $db_script_url has to be changed from:
$db_script_url = $db_dir_url ."/db.cgi";
to:
$db_script_url = "/cgi-bin/db/db.cgi"; [The local path to the script relative to the web server root.]

I also had to apply the Xitami web server hack in the FAQ as the RAQ does not authenticate properly.

Thanks to all who helped!
