Sending data to a webserver with GPRS/GPS Shield ( Sara G-350) using Arduino UNO

I am working on a project for sending data to a webserver with HTTP protocol (GET or POST method).
my problem is in the meaning and perpose of ""responseFilename"" and how could i work with it?
the Filename where the HTTP server response will be stored.

Here is my approach:

#include <SoftwareSerial.h>
#include <String.h>


SoftwareSerial gprsSerial(7 ,8);

void setup() {
  // put your setup code here, to run once:
  gprsSerial.begin(19200);                
  Serial.begin(19200);     
  delay(2000);

 gprsSerial.println("AT+CGDCONT=3,\"IP\",\"weborange\"");
 toSerial();
 delay(2000);

 gprsSerial.println("AT+UHTTP=0");
 toSerial();
 delay(2000);
 gprsSerial.println("AT+UHTTP=2,1,\"www.navtec.16mb.com\"");
                   //AT+UHTTP=<profile_id>,<op_code>,<HTTP_server_name>
 toSerial();
 delay(2000);

 gprsSerial.println("AT+UHTTP=0,5,80");
 toSerial();
 delay(2000);

}

void loop() {

 //gprsSerial.println("AT+UHTTP=2,1,\"submit\"");
                    //AT+UHTTP=<profile_id>,<op_code>,<param_val>[,<param_val1>]
 //toSerial();
 //delay(2000);

 gprsSerial.println("AT+UHTTPC=2,1,\"/add.php\",\"filename\"");  //Problem here!!!!!!!!
                   //AT+UHTTPC=<profile_id>,<http_command>,<path>,<filename>[,<param1>[,<param2>[,<param3>]]]
 toSerial();
 delay(2000);
}

void toSerial()
{
  while(gprsSerial.available()!=0)
  {
    Serial.write(gprsSerial.read());
  }

}

This is what I get:

+CGDCONT=3,"IP","weborange"

OK +UHTTP=0

OK +UHTTP=2,1,"www.navtec.16mb.com"

OK +UHTTP=0,5,80

OK +UHTTPC=2,1,/add.php,filename

ERROR +UHTTPC=2,1,/add.php,filename

ERROR +UHTTPC=2,1,/add.php,filename

ERROR +UHTTPC=2,1,/add.php,filename

ERROR ...

Thanks for your time, I am waiting for your support, any ideas could help. Sorry for my bad English

A shield only fits one way. If you can't manage to attach a shield correctly, I fear that writing any useful code is way beyond you.
