PicketLink allows you to configure a path to logout users. To configure a logout path just do:

httpBuilder
    .forPath("/logout")
        .logout()

Here, the logout method will mark the given path as a point of logout. In this case, when a request arrives to this path PicketLink will logout the user.

In some cases you may want to redirect the user to a specific path after a successful logout. For that you just need to:

httpBuilder
    .forPath("/logout")
        .logout()
        .redirectTo("/goodbye.html");
