HTTP post initiates new session -- need to avoid it.

[Information Guzzler]

The application is designed to generate HTTP post request to a URL with
couple of parameters. The response to this request needs to be displayed in
a new browser window. This new window will generate all future request to
the application.

I use HttpClient to generate the request to the new URL which has the same
context. The problem arises when the post request is generated, a new
session is created and the response is displayed.

At this point there are 2 jsessions active- the one with which the Http
request was generated and the other which was initiated to display the
reponse in new window.

When I try to use the application in the new window it uses the initial
session and hence does not find the application related session attributes
which are stored in the session used to display the response.

I need to avoid the creation of new session when a new window is opened to
display the reponse to Http post request.

I use the following

String url = "http://localhost:8085/app/Login.do";;

HttpClient client = new HttpClient();
    client.getState().addCookie(new Cookie("localhost:8085","jsessionid",
request.getSession().getId(), "app", null, false));
    PostMethod method = new PostMethod( url );


  // Configure the form parameters
  method.addParameter( "encryptedData", encryptedData );
  method.addParameter( "HMAC", HMAC);
  method.addParameter( "jsessionid", request.getSession().getId());



    log.info("Open browser"+url);
    int statusCode;
  // Execute the POST method
    try
    {
     statusCode = client.executeMethod(method);
    }
    catch(IOException e)
    {
     statusCode = -1;
     log.info("IOexception");
    }
    log.info("status code"+statusCode);
    if( statusCode != -1 ) {
      String contents = method.getResponseBodyAsString();
   response.setContentType("text/html");
   PrintWriter out = response.getWriter();
   out.println(contents);
      method.releaseConnection();
