You should use CGI to do that: en.wikipedia.org/wiki/Common_Gateway_Interface Also there is ISAPI if you are on Windows platform: en.wikipedia.org/wiki/… — Andrew Komiagin

Unless you know exactly what you're doing, someone will probably figure out how to exploit your program to gain sufficient access to the host to use it as a bot/gateway. Just be careful/absolutely certain this is the approach you want to take. — Mark B

The simplest CGI app looks like this:

#include <iostream>
using namespace std;

int main ()
{

   cout << "Content-type:text/html\r\n\r\n";
   cout << "<html>\n";
   cout << "<head>\n";
   cout << "<title>Hello World - First CGI Program</title>\n";
   cout << "</head>\n";
   cout << "<body>\n";
   cout << "<h2>Hello World! This is my first CGI program</h2>\n";
   cout << "</body>\n";
   cout << "</html>\n";

   return 0;
}

Once your program is uploaded to the web server, you'll want to be sure to move it to your cgi-bin (or public_html directory — wherever your ISP has told you to put your CGI programs). Then you'll also need to change the permissions on the file so that it is "executable" (or runnable) by the system. The Unix shell command for this is: chmod 755 filename
