How can I do several request in one HttpURLConnection with Java?

 URL url = new URL("http://my.com");
 HttpURLConnection connection = (HttpURLConnection)url.openConnection();
 HttpURLConnection.setFollowRedirects( true );
 connection.setDoOutput( true );
 connection.setRequestMethod("GET"); 

 PrintStream ps = new PrintStream( connection.getOutputStream() );
 ps.print(params);
 ps.close();
 connection.connect();
 //TODO: do next request with other url, but in same connection

Thanks.

From the Javadoc:

Each HttpURLConnection instance is used to make a single request.

The object apparently isn't meant to be re-used.

Aside from a little memory thrashing and inefficiency, there's no big problem with opening one HttpURLConnection for every request you want to make. If you want efficient network IO on a larger scale, though, you're better off using a specialized library like Apache HttpClient.
