Can you transport data from one webapp to the other when you use the sendRedirect() method? Here is my true problem. I want to transport data such as a username and a password between two webapps (and I don't want to use URL rewriting). The user logs on Webapp1 and after authentification, the user has the choice to go to Webapp2, and I need the username and password to work in Webapp2. As I understand it, I can't use the session object to transport data because each Webapp has it's own session object. So I thought of using the forwarding method and use the request object to store my data (with setAttribute and getAttribute). It works, but like I said in my previous email, after forwarding, I'm still in the context of Webapp1.

I am not sure if this helps, but a forward happens at the server so the server makes the forwarded request and returns the results to the browser, so the browser never knows the request has changed and therefor the URL in the browser will not change, on the other hand a redirect tells the browser to go get the new page so the browser URL will update to the new URL.John > -----Original Message-----> > > I need help.
