Subject: session tracking problem in doGet
>Hi,
> I am writing a servlet handler program. The process is: when user login,
my
>handler servlet read login information and pass them to loginServlet, save
>loginServlet's sessionId and display result. Then user can edit his
account
>through Get method of 'updateServlet '. My handler servlet will pass
>loginServlet's sessionId to updateServlet.
> But when I use req.getSession(true) in updateServlet, what I got is
>different with the sessionid i sent. Please help me.
>Here is my code:
>
> handlerServlet:
>public sendGetData(String lastCookie)
>{
> URL url=new URL("/servlet/updateServlet?Change=add");
> URLConnection con = url.openConnection();
> con.setDoInput(true);
> con.setUseCaches(false);
> if(lastCookie!=null)
> con.setRequestProperty("cookie", lastCookie);
>
> InputStream in = con.getInputStream();
> Reader reader = new InputStreamReader(in);
> this.reader = new BufferedReader(reader);
>}

>updateServlet:
> doGet()
>{
> HttpSession session=req.getSession(true) ;
