Hi,
I have created two servlet: one will create a cookie (createCookie) and
another is to retrieve the cookie (retrieveCookie). The retrieveCookie will
get the cookie based on the specified cookie name. I placed these servlets
in two different servers.
First of all, I invoke the createCookie servlet to create a cookie from the
server (IP: 192.168.4.90)
And i have checked that there is a update in cookies.txt (Netscape) because
there is a new info which has the 192.168.4.90 as the IP address and so on.
After that, I start the retrieveCookie servlet from another server (IP:
192.168.4.190) which can retrieve that particular cookie.
Then I change the contents of the cookie: 192.168.4.90 to 192.168.4. 190.
I invoke the retrieveCookie again but it can't get that particular cookie.
So, my question is how to get a cookie from a server but that cookie is not
belonged to that server? How to get the IP address from a cookie?
Below is the code of retrieveCookie.java:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class RetrieveCookie1 extends HttpServlet {
public void doGet (HttpServletRequest request,HttpServletResponse
response)
throws ServletException, IOException {
String Name, Value;
Cookie[] cookies = request.getCookies();
for(int i=0; i<cookies.length; i++) {
Cookie thisCookie = cookies[i];
if (thisCookie.getName().equals("User")) {
Name = thisCookie.getName();
Value = thisCookie.getValue();
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>" +
"<head><title> Retrieve Cookie
</title></head>" +
"<strong> Cookie </strong><br>" +
"Name: " + Name + "<br>" +
"Value: " + Value + "<br>" +
"</html>");
}
else {
PrintWriter out = response.getWriter();
out.println("<html>" +
"<head><title>Retrieve
Cookie</title></head>" +
"<strong>Cookie </strong><br></html>");
}
}
}
}
Can anyone help me with this?
Thank You.
