How to create a BASIC/MINIMALISTIC WIN CGI program with Delphi.
The code works with LilHTTP web server and any other that supports
WIN CGI's. The calling web page will have to pass two varibles.
The persons name and their email address. The CGI will take the name
and email address from the command line and place it into the HTML
code where apropriate and send the information back to the host.
You can add code to store the information into a database or file
if you wish.

Diese Methode eignet sich zur Erzeugung von WIN-CGI Module mit minimaler
Anforderungen. Lauffähig unter den gängisten Web-Servern.
eMail-Adresse und Name werden abgefragt und in einer HTML-Antwortseite
zurückgeliefert. Eine Anbindung an einer Datenbank dürfte sich leicht
realisieren lassen.
