My first CGI was using Informix-4GL. If you're familiar with 4GL, you might emote "you what!?". It was a very crude tech demo, it was the hammer I had and shortest path the database data, and it was not a good fit. But that's kind of the point. Ye Olde "request -> stdin -> program -> stdout -> response" makes the computing piece very tech agnostic. My second foray was using SIOD (Scheme in One Defun). It had marginal HTTP/CGI support. More than enough for my purposes: running, caching, and rendering SQL reports from text files to PDF so they can be downloaded. Those were internal projects, nothing on the public internet. But it just helps to demonstrate the flexibility of CGI in a new world of interconnectivity when the tech and tools were still forming and cooling out of the heated plasma of the new age.
