I don't understand what you don't understand in Gambas and CGI.

By using the gb.web component, your Gambas project becomes a CGI 
application (or CGI script or whatever you want to call it) :

- the gb.web component takes the CGI environment variables and present 
them with a nice ASP-like interface.

- The Request class analyzes the HTTP request for you: it can understand 
GET arguments, POST arguments, handle file uploads for you.

- The Response class allows you to send a response with its Mime 
datatypes, and other custom HTTP headers.

I don't understand your story of having a "CGI module" (what's that?) 
and a "main application".

So, please elaborate.
