Re: Session var read by form C++ CGI prog ?

Thanks, very much, Raditha. Do you mean to pass my variable as a cgi parameter ? If so, the problem is that this file that is being uploaded via the form to the program MyCppProg.exe gets sent as THE input to the prog, apparently as a cgi-type parameter through stdin (i.e. cin), so that when I try to pass the value as a cgi parameter, it gets inserted INTO the file that is being uploaded. Am I understanding correctly, or did I miss the point ?
