Java - HttpURLConnection getFollowRedirects() Method

Quiz

The Java HttpURLConnection getFollowRedirects() method returns the value of this HttpURLConnection's instanceFollowRedirects field.

Declaration

Following is the declaration for java.net.URLConnection.getInstanceFollowRedirects() method

public boolean getInstanceFollowRedirects()

Parameters

Return Value

the value of this HttpURLConnection's instanceFollowRedirects field.

Exception

Example 1

The following example shows the usage of Java HttpURLConnection getInstanceFollowRedirects() method for a valid url with https protocol. In this example, we're creating an instance of URL class. Using url.openConnection() method, we're getting the HttpURLConnection instance. Using getInstanceFollowRedirects(), we're checking the instanceFollowRedircts flag value printing the same. Now using setInstanceFollowRedirects() method, we're changing the value of instanceFollowRedircts flag and printing the same again −

package com.tutorialspoint;

import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;

public class HttpUrlConnectionDemo {
   public static void main(String [] args) {
      try {
         URL url = new URL("https://www.tutorialspoint.com/index.htm?language=en#j2se");
         HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
         urlConnection.connect();  
         System.out.println("Connected.");  

         boolean result = urlConnection.getInstanceFollowRedirects();
         System.out.println("getInstanceFollowRedirects: " + result);  

         urlConnection.setInstanceFollowRedirects(false);
         result = urlConnection.getInstanceFollowRedirects();
         System.out.println("getInstanceFollowRedirects: " + result); 

         urlConnection.disconnect();
         System.out.println("Disconnected.");  
      } catch (IOException e) {
         e.printStackTrace();
      }
   }
}

Let us compile and run the above program, this will produce the following result −

Output

Connected.
getInstanceFollowRedirects: true
getInstanceFollowRedirects: false
Disconnected.
