How to send http strings

Hello,

Thanks for the answer, is that the only chance?
I was expecting a simple solution, send the string and that's it.
Can you point me a direction to follow.
here what i could do until now

#include <Ethernet.h>
#include <SPI.h>

byte mac[] = { 0x90, 0xA2, 0xDA, 0x00, 0x35, 0x6C }; // define mac
EthernetServer server = EthernetServer(80); // define server port

void setup(){
  Serial.begin(9600); // activat serial port

  pinMode(2, OUTPUT); // LED indicator for camera ON 
  pinMode(3, OUTPUT); // LED indicator for position 1
  pinMode(4, OUTPUT); // LED indicator for position 2
  pinMode(5, OUTPUT); // LED indicator for position 3
  pinMode(6, OUTPUT); // LED indicator for position 4
  pinMode(14, INPUT); // Push button for camera ON
  pinMode(15, INPUT); // Push button for position 1
  pinMode(16, INPUT); // Push button for position 2
  pinMode(17, INPUT); // Push button for position 3
  pinMode(18, INPUT); // Push button for position 4
  
  Ethernet.begin(mac); // register mac with DHCP
  server.begin(); //start net server
  Serial.println(Ethernet.localIP()); // print IP local
}

void loop(){
//test buttons
  testCAM(14);
  testinput(15);
  testinput(16);
  testinput(17);
  testinput(18);
} 

void testCAM(int pin){
//test input and activate output.  
          if (digitalRead(pin) == LOW){
             digitalWrite (2, HIGH);} //activate LED
             //http://192.168.1.100:8081/?L1=1 //Send string
          else{
             digitalWrite (2, LOW);}
             //http://192.168.1.100:8081/?L1=0 //Send string
}
void testinput(int pin){
//test input and activate output.  
          if (digitalRead(pin) == LOW){
             digitalWrite ((pin-12), HIGH);} //activate LED
             //http://192.168.1.100:8085/Set?Func=PresetCntPos&Kind=1 //Send string
          else{
             digitalWrite ((pin-12), LOW);}
}

Thanks again.
