I have a JSF application that has the following bug in it. When I successfully login in to the application through a login page (form authentication), I am sent to the first page of my application. If I hit the browswer back button, I am sent back to my login page where I can login again (even though I am already logged in). Another successful login sends me to the first page of my application, but this time the login form is appended to the bottom of the page. Any idea why? I am using a POST-redirect-GET pattern if that matters.
