From SparkfunWifiShield to ArduinoWebserver

I am trying to send to send data from a SparkfunWifiShield to a arduino webserver that is created with a ethernet shield. I used this code: Arduino - Webserver with an Arduino + Ethernet Shield | Random Nerd Tutorials

I am now trying to send some kind of POST data with the wifishield. Eventually I want to use a button that can control the led.

Current code of WifiShield:

#include <SoftwareSerial.h> // Include software serial library, ESP8266 library dependency
#include <SparkFunESP8266WiFi.h> // Include the ESP8266 AT library
ESP8266Client client; // Create a client object
int x = 1;
void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);



if (esp8266.begin()) // Initialize the ESP8266 and check it's return status
    Serial.println("ESP8266 ready to go!"); // Communication and setup successful
else
    Serial.println("Unable to communicate with the ESP8266 :(");


int retVal;
retVal = esp8266.connect("****", "****");
if (retVal < 0)
{
    Serial.print(F("Error connecting: "));
    Serial.println(retVal);
}

retVal = client.connect("***", 80); // Connect to sparkfun (HTTP port)
if (retVal > 0)
    Serial.println("Successfully connected!");
}

void loop() {
/*client.print("data" + String(x) + "\n\n");
Serial.println(x);
delay(1000);
x++;*/

/*client.print("POST /?buttonScoreThuisPlus=1");
delay(1000);*/

}

Code of webserver:

Hoi Vincent11155, welkom op het Nederlandstalige gedeelte.

In dit gedeelte spreken we gewoon Nederlands, om zo eventuele taalbarrières weg te nemen.
Ik zie dat je in dit onderwerp een tijdje terug al wat vragen hebt gesteld.
In de code die je daar laat zien, komen Nederlandse teksten voor dus ik neem aan dat dat je dagelijkse voertaal is.
In dit nieuwe onderwerp hier op het Nederlandstalige gedeelte heb je alleen een mededeling gedaan en laat je 2 voorbeeld sketches zien, maar je hebt geen vraag gesteld.

Dus wat is je vraag ?

Ik probeer om een GET request te sturen naar een webserver om zo dan een waarde aan te passen. De webserver word aangemaakt door een ethernetshield. maar ik kan maar geen succevolle manier vinden om dat te doen. Sorry als ik het niet zo goed kan uitleggen.

Ik heb een oplossing gevonden door een site refresh te sturen naar de webserver.
client.println("Refresh: 4;URL='//192.168.0.149/?buttonScoreThuisPlus'>");
door dit te doen kan ik de waarde veranderen van het scorebord.
