response.sendRedirect不跟踪ip

Question

i have a redirect on login.jsp to index.jsp with this syntax:

response.sendRedirect("index.jsp");

on the server when I'm accessing on localhost:8080 testing the application it works fine. when I'm browsing remotely from another PC, and i need that server address (like xxx.xxx.xxx.xxx:8080) that redirect sends me to localhost:8080/index.jsp which of course doesn't exist on local machine. If i write something like

response.sendRedirect("xxx.xxx.xxx.xxx:8080/index.jsp");

then the browser loses the session variables, which i do not want. how to solve this?

Answer 1

Try using requestDispatcher.forward() instead of response.sendRedirect()..

This will work...

Answer 2

Try this

response.sendRedirect("/yourWebContext/index.jsp");

this will work

xxx.xxx.xxx.xxx:8080/index.jsp

looses the session may be because browser doesn't send the cookie it has recieved for the with different domain name
