using request.sendRedirect??

[Joe Schaffer]

Hi everybody,
I have the following Problem:
When a user wants to access the userpage he has to perform a login first. I have done this with a LoginHandler. There the user enters his username and depending on a known username he will be forwarded with the command request.sendRedirect("URL");
My Problem is, I also need the username and maybe even some other data forwarded to the servlet. What I do not want to do is to forward it with
?user=name&...
If I perform request.getParameter("name"); after I redirected the page the data I had in there is gone.
Is there another command how to call this new URL and send the data similar to a function call? functioncall("URL",name,data...);
Thanks for your help
Joe

use Session or Servletcontext to persist data between the servlets.eg before redirecting add the username to session by
request.getSession().setAttribute("Username","value");
and retrieve it in destination URL by
String name = request.getSession().getAttribute("Username");
(note this is when Session is Active).

using session is better than URL rewriting in this case.

Or don't do a redirect and instead forward the request to the page. The user credentials will then still be available.

Maybe another way of thinking : use declarative security instead and let the webserver handle your security problems.
In such a situation you don't need sendRedirect at all.
When you don't like this way of thinking : indeed, use forward and your request-parameters will still be available.
