Example 2: esp8266 wifi example

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();
