Nothing happens when i make HTTP request from my arduino with wifly

I'm using arduino UNO R3 with wifly RN-XV rev3. I'm trying to make HTTP request from arduino but nothing happens. This is my code:

wifiSerial.listen();
 if (client.connect("tatkartr.com", 80)) {
    client.println("POST /checkin/auto_checkin.php?band=1234567890qw HTTP/1.1");
    client.println("Host: 192.232.249.168");
    client.println();
    Serial.println("connected");
  } else {
    Serial.println("connection failed");
  }

In this code keep on receiving connected continuously but nothing happens, when I swap the domain name with the IP then there is no response from the arduino. Any help would be appreciated.

The Host parameter is incorrect. It must be your domain name for your virtual server.
It appears to be a GET request, not a POST request.
Maybe your wifly is having trouble resolving tatkartr.com.

if (client.connect("tatkartr.com", 80)) {
    client.println("GET /checkin/auto_checkin.php?band=1234567890qw HTTP/1.1");
    client.println("Host: tatkarter.com");
    client.println();
    Serial.println("connected");
} else {
    Serial.println("connection failed");
}

You should post all your code, not just a snippet. I can't tell what you do after this.
