Using forward changes control within the server, while sendRedirect transfers control to the browser and asks it to make another request. Hence forward is faster, but the browser won't know what you did, and won't know about any directory location changes. This also means that a change from http to https in a forward would be pointless since it does not involve communication with the client.
As for setting parameters with a forward, you're on the right track. Adding them to your target string works for me.

Or add a filter with a servlet request wrapper mapped to index.jsp that checks and adds parameters as needed.
