Hi.
under Windows

My sequence is:

torquebox run in other command windows
firefox to http://localhost:8080/backstage/. Requires authentication . Good. Enter user and password. Good. I am on page.
cd %myapp%
torquebox deploy
torquebox undeploy
torquebox deploy

firefox to http://localhost:8080/backstage/. Requires authentication . Good. Enter user and password. Again Requires authentication.
