servlet requires refresh to show cookie values

[tushar panda]

the servlet shown below requires a refresh to show cookies values.

servlet :

 package books;  
 import java.io.* ;  
 import javax.servlet.* ;  
 import javax.servlet.http.* ;  
 import javax.servlet.http.Cookie;   
 import java.lang.String ;  
 import java.util.* ;  
   
 public class regfound extends HttpServlet {  
 public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException{  
 response.setContentType("text/html");  
 PrintWriter out = response.getWriter();  
 Boolean regis=false;  
 String regcookiefound = "no";  
 Cookie[] c = request.getCookies();  
 if(c!=null){  
 for(int i=0;i<c.length;i++)  
  { Cookie c1=c[i];  
     if((c1.getName().equals("regcookie"))&&(c1.getValue().equals("qwerty")))  
     {regis = true;regcookiefound = "yes";
      out.println("--"+c[i].getName()+"--");
     out.println("--"+c[i].getValue()+"--");break;  
    }  
  }  
 }  
 if(!regis)  
 { Cookie reguser = new Cookie("regcookie","qwerty");  
    response.addCookie(reguser);  
 }  
 }  
 } 

actually is should show retrieved cookie's name and retrieved cookie's value but i require to refresh it to get those values.

Cookies are a client-side concept. The servlet does not create the cookie, it merely creates headers that tell the browser to create the cookie. Until the headers have been seen by the browser, the cookie does not exist.
