HttpsURLConnection getHeaderFields does not return set cookie

Question

I am sending a request for a single HTTPS URL, and somehow I get a null value for the "Set-Cookie". When I repeat, I see that the header key has a "set-cookie", but the header value approaches as null.

Here is my code:

URL obj = new URL(url);
HttpsURLConnection conn = (HttpsURLConnection) obj.openConnection();
HttpsURLConnection.setFollowRedirects(false);


conn.setRequestProperty("User-Agent", USER_AGENT);
conn.setRequestProperty("Accept",
            "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
conn.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
conn.setRequestProperty("Connection", "keep-alive");
conn.setRequestProperty("Accept-Encoding", "gzip, deflate");
conn.connect();

Map em = conn.getHeaderFields();
System.out.println("header Values......" + em.toString());

String headerName = null;   

for (int i = 1; (headerName = conn.getHeaderFieldKey(i)) != null; i++) 
{
     System.out.println("Header Nme : " + headerName);
     System.out.println(conn.getHeaderField(i));

}

Output:

header Values ​​...... {null = [HTTP / 1.1 200 OK], x-wily-info = [Clear guid = 0BE0EC9D0A7E67816C471FA946FD2EBB], Date = [Sat, 29 Mar 2014 03:27:41 GMT], Content- Length = [8106], x-wily-servlet = [*******************], X-FRAME-OPTIONS = [SAMEORIGIN], Connection = [close], Content-Type = [text / html; charset = UTF-8]}
