I am trying to understand how the info is passed from the webform to the application written in C. Specifically, function  ParseRequest in ndso.c. There is some interesting loop logic there which is less than clear without documentation. Is there a Wiki or a HOWTO available somewhere which would explain the content of character arrays "getvars" and "postvars"?

You may need to read some CGI application programming doc. The C application can read the form data from std input stream.

Sonic:

thanks a lot for the pointer to CGI programming. This info will be very useful to me.

I am now dissecting the ndso. It looks like a great demo app to me. However, there was not quite enough documentation concerning its internal structure, parameter passing, and which function is doing what. This kind of docu would not be needed if ndso was a final app, but it would make sense to make ndso a starting point for other developers, esp. non-experts in CGI.
