I need to redirect to the final page once the dhcp assigns new IP after the initial setup without browsing my network or serial connection. similar to initial redirection for setup, where can i set this?

`#include <ESP8266WiFi.h>
#include <DNSServer.h>
#include <ESP8266WebServer.h>
#include <WiFiManager.h> // https://github.com/tzapu/WiFiManager

// Set web server port number to 80
WiFiServer server(80);

// Variable to store the HTTP request
String header;

// Auxiliar variables to store the current output state
String output5State = "off";
String output4State = "off";

// Assign output variables to GPIO pins
const int output5 = 0;
const int output4 = 2;

void setup() {
Serial.begin(115200);

// Initialize the output variables as outputs
pinMode(output5, OUTPUT);
pinMode(output4, OUTPUT);
// Set outputs to LOW
digitalWrite(output5, LOW);
digitalWrite(output4, LOW);

// WiFiManager
// Local intialization. Once its business is done, there is no need to keep it around
WiFiManager wifiManager;

// Uncomment and run it once, if you want to erase all the stored information
//wifiManager.resetSettings();

// set custom ip for portal
//wifiManager.setAPStaticIPConfig(IPAddress(10,10,10,69), IPAddress(10,10,10,1), IPAddress(255,255,255,0));

// fetches ssid and pass from eeprom and tries to connect
// if it does not connect it starts an access point with the specified name
// here "AutoConnectAP"
// and goes into a blocking loop awaiting configuration
//wifiManager.autoConnect("AutoConnectAP");
// or use this for auto generated name ESP + ChipID
wifiManager.autoConnect();

// if you get here you have connected to the WiFi
Serial.println("Connected.");
server.begin();
}

void loop() {
WiFiClient client = server.available(); // Listen for incoming clients
if (digitalRead(0) == HIGH)
{
WiFi.disconnect(true);
delay(2000);
ESP.reset();
}
if (client) { // If a new client connects,
Serial.println("New Client."); // print a message out in the serial port
String currentLine = ""; // make a String to hold incoming data from the client
while (client.connected()) { // loop while the client's connected
if (client.available()) { // if there's bytes to read from the client,
char c = client.read(); // read a byte, then
Serial.write(c); // print it out the serial monitor
header += c;
if (c == '\n') { // if the byte is a newline character
// if the current line is blank, you got two newline characters in a row.
// that's the end of the client HTTP request, so send a response:
if (currentLine.length() == 0) {
// HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)
// and a content-type so the client knows what's coming, then a blank line:
client.println("HTTP/1.1 200 OK");
client.println("Content-type:text/html");
client.println("Connection: close");
client.println();

        // turns the GPIOs on and off
