HttpURLConnection getResponseCode 302

The HttpURLConnection‘s
follow redirect is just an indicator, in fact it won’t help you to do
the “real” http redirection, you still need to handle it manually.

URL obj = new URL(url);
HttpURLConnection conn = (HttpURLConnection) obj.openConnection();
conn.setInstanceFollowRedirects(true);  //you still need to handle redirect manully.
HttpURLConnection.setFollowRedirects(true);

1. Java Http Redirect Example

If a server is redirected from the original URL to another URL, the response code should be 301: Moved Permanently or 302: Temporary Redirect. And you can get the new redirected url by reading the “Location” header of the HTTP response header.

For example, access to the normal HTTP twitter website – http://www.twitter.com , it will auto redirect to the HTTPS twitter website – https://www.twitter.com.

package com.mkyong.http;

import java.io.BufferedReader;

import java.io.InputStreamReader;

import java.net.HttpURLConnection;

import java.net.URL;
public class HttpRedirectExample {
  public static void main(String[] args
