Getting the Response Headers from an HTTP Connection
try {

URL url = new URL("http://hostname:80");

// List all the response headers from the server.
// Note: The first call to getHeaderFieldKey() will implicit send
// the HTTP request to the server.
for (int i=0; ; i++) {
String headerName = conn.getHeaderFieldKey(i);
String headerValue = conn.getHeaderField(i);
if (headerName == null && headerValue == null) {
// No more headers
break;
}
if (headerName == null) {
// The header value contains the server's HTTP version
}
}
