Hi Experts again.
This one is quite special. How do web servers pass the parameters to any side applications (CGI, PHP etc.) and how does the sever catch the result from the CGIs? I know the CGIs simply write to console and the server must catch this. I also know that the CGIs read the system variables for the params from the server but it really seems strange to me. What if the cgi receives a file? Please, tell me if you have any experience.
