Hello All,
I am a servlet new one.
In my sample servlet, I use session to count the client number.
here is my servlet:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class SessionServlet extends HttpServlet
{
String sessionId= null;
public void doGet (HttpServletRequest request,HttpServletResponse response)
throws ServletException, IOException
{
Integer visitCounter=null;
HttpSession clientSession=request.getSession(true);
if (clientSession.isNew())
{
visitCounter=new Integer(1);
clientSession.putValue("visitCounter",visitCounter);
}
else
{
visitCounter=new Integer(
((Integer)clientSession.getValue("visitCounter")).intValue()+1);
clientSession.putValue("visitCounter",visitCounter);
}
sessionId=clientSession.getId();
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("session id:"+sessionId);
out.println("<p>");
out.print("You have visited "+visitCounter+" times.");
out.println("<p>");
out.close();
}
}
every time I click "refresh" button, the counter will add one, but I
found that wehn I open another browser, the sessionID is still the
previous sessionID, and the counter is not 1 but the previous number
adding one. The browser I use is IE4.0, and Netscape4.5, they have the
same probleom.
Any one who know about that or has any idea about please tell me,
thanks a lot.
Best regards,
