I have a link to a .csv which looks like this:

http://website.com/data.csv?since=2019-03-21T00:00Z&sensor=xxx

My method get this link as URL

BufferedReader in = new BufferedReader(new InputStreamReader(URL.openStream()));

The problem is that it is not properly downloading .csv. I have realized that if I add 'amp;' after & it works properly. Is there any easy way to work this out?

I have found the solution: https://www.mkyong.com/java/java-httpurlconnection-follow-redirect-example/

public URL getFinalUrl(URL url) 
 try 
 HttpURLConnection conn = (HttpURLConnection) url.openConnection();
 conn.setReadTimeout(5000);
 conn.addRequestProperty("Accept-Language", "en-US,en;q=0.8");
 conn.addRequestProperty("User-Agent", "Mozilla");
 conn.addRequestProperty("Referer", "google.com");

 boolean redirect = false;

 int status = conn.getResponseCode();
 if (status != HttpURLConnection.HTTP_OK) 
 if (status == HttpURLConnection.HTTP_MOVED_TEMP
 
 String newUrl = null;
 if (redirect) 
 // get redirect url from "location" header field

 // get the cookie if need, for login
