java httpurlconnection 403 but not on web browser

Today i face with a issue when i use java HttpUrlConnection to connect to a site i alway get http code 403. I finally over come that issue after loose a couple of hours. So i write down here  a post and hope can help much people on this prolem. When you search and come to this post i think you can quickly find out solution here.


Some sites will enable to reject when connect to by none browser tool and our connect using HttpUrlConnection violate this rule so the site do not allow to connect.


To solve this issue we can bypass the rule by setting agent header for our connect to those sites

URL url= new URL("site you need connect here");

HttpURLConnection hConnection = (HttpURLConnection) url.openConnection();

hConnection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11");
