I don't know this is suitable for u. I not, please excuse me.
My suggession is use a ISAPI dll. put that dll in Web server.

Or

U can use the Netscape SDK for plug-in from Nestace site. Then u can get the data from the client side.

GOOD LUCK

See http://hoohoo.ncsa.uiuc.edu/cgi/env.html
as a reference.

The following example will render this data as HTML:

#include <stdio.h>
#include <strings.h>
#include <stdlib.h>

/* Compile:
   gcc  -Wall -pedantic -pipe -O5 -o user-data user-data.c
*/  

#include <stdio.h>
#include <strings.h>
#include <stdlib.h>

int main(void) {

char* pszUser = getenv ("REMOTE_USER"); // user name
char* pszAuth = getenv ("REMOTE_AUTH"); // auth info


  puts("Content-type: text/html\n");
  puts("<HTML><HEAD><TITLE>USER DATA</TITLE></HEAD>");
  puts("<CENTER><H1 ALIGN=CENTER> Here's your user data:</H1>%s %s<HR><H2>", pszUser, pszAuth);
  puts("</H2></BODY></HTML>");
}
