CGI app and restart on every request?

Question

IIS

It is required to make a CGI application. The server sends an html page, into a form on the html page, something is entered and sent to the cgi server to the application, the application sends a response to the client.
As far as I know, according to technology, the server must open the application every time for each request. How in this case to process several requests from one client (1st for html and 2nd with form content) or is it impossible using CGI technology? And you need to send html from another server.
IIS, C#, I/O via console will be used.

Answer 1

Now in C#, the main way to create web applications is asp net core.
It is much faster than CGI and other bells and whistles of the 2000s.

Answer 2

I just can’t understand you that different forms are given to different clients? It seems that the form should always be the same, but the answer is based on the results of the form.
