Go to link using if condition using Arduino IDE

I'm just trying to get myself here "http://192.168.1.103:30000/?k=23&v=capture" when an if condition meet its requirement.

#include <ESP8266WiFi.h>
// I purposely don't include the ssid and ssid1 here
WiFiServer server(80);

void setup() {
  pinMode(1, INPUT);
  Serial.begin(115200);
  delay(10);
  Serial.println();
  WiFi.softAP(ssid1, password1);
  Serial.println(WiFi.localIP());
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);
  WiFi.mode(WIFI_AP_STA);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
  // Start the server
  server.begin();
  Serial.println("Server started");
}

void loop() {
  String link = "http://192.168.1.103:30000/?k=23&v=capture";
  WiFiClient client = server.available();
  if (!client) {
    return;
  }
  int var = digitalRead(1);
  if (var == HIGH) {
    client.print(link);
  }

Let's say:

  1. I already run Chrome.
  2. How can that link above be called without even typing it on Chrome? I want to connect to it automatically.

Any method you could teach? I got the feeling this code itself is wrong. Thanks.

void setup() {
  Serial.begin(9600);
  lcd.begin(16, 2);
  // initialize the lcd for 16 chars 2 lines, turn on backlight

First understand a fact that you doesn't need google chrome for requesting a website.

 client.println("GET /?k=23&v=capture");
 client.println("Host: 192.168.1.103");

What you do in the above line is that you request for /?k=23&v=capture addressed content in the ip address 192.168.1.103, Actully this is what you do when you use a google chrome. On PC you require a google chrome (or any other browser) for web site request because its difficult to request using commands each time (Think of requesting for a single page using a hell of http commands instead of using chrome, Ohh that's mess). So understand chrome isn't needed to access a site.
