Loosing my HttpSession between Applet and Servlet

[De...@hydro.qc.ca]

Hi,
 
I'am using HttpClient 4.0.1.
 
Each time my applet make a get or post to the servlet, I am loosing my httpSession on the back end.
 
How can we keep the httpSession alive with HttpClient ?
 
Here's the call that I made from my applet, each time it is call, i get a new httpSession from my servlet :
 
public static void getHttp(TestHttpSession applet) {

try {

HttpClient clientHttp = new DefaultHttpClient();

HttpResponse response = clientHttp.execute(httpGet);

HttpGet httpGet = new HttpGet(applet.getURL());

clientHttp.getConnectionManager().shutdown(); 

} catch (Exception e) {

e.printStackTrace();

}

}

Thanks,
Frank

No wonder the HTTP session does not stick, as you are creating a new
instance of HttpClient for each request. When HttpClient instance goes
out of scope, you lose all state information contained in it.
