As far as i know HttpSession internally uses Cookies and if it is disabled then uses URL rewriting.....
i tried with small piece of code creating HttpSession and setting one attribute to it
I disabled my browser cookies......
Now when i run the program with cookies disabled n no url rewriting i did......still im able to get the attribute which i set on session....how come that is possible.....
Please guide me how it is working.....
Here is my code which i tried....
web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app
<
servlet>
<servlet-name>MyServlet</servlet-name>
<servlet-class>com.sas.zip1.ServletClass</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>MyServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>MyServlet1</servlet-name>
<servlet-class>com.sas.zip1.ServletClass1</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>MyServlet1</servlet-name>
<url-pattern>/session2.spring</url-pattern>
</servlet-mapping>
</web-app>
ServletClass
public class ServletClass extends HttpServlet{
public void doGet ( HttpServletRequest request,
HttpServletResponse response )throws ServletException, IOException {
PrintWriter out;
HttpSession sson=request.getSession();
sson.setAttribute("nammee", "jisnussstttttt");
response.setContentType("text/html");
out = response.getWriter();
out.println("<HTML><HEAD><TITLE>");
out.println(" Use of cookie in servlet");
out.println("</TITLE></HEAD><BODY><form method=get action=session2.spring>");
out.println(" <input type=submit><b>This is a Cookie example</b>");
out.println("</form></BODY></HTML>");
out.close();
}
}
ServletClass1
public class ServletClass1 extends HttpServlet{
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse resp)throws ServletException, IOException {
System.out.println("INSIDE NEW ServletClass1");
HttpSession session=request.getSession(false);
System.out.println("ID IS :"+session.getId()+ "VALUE IS : "+session.getAttribute("nammee"));
}
}
Please Help me out......Thanks
