As this seems to be a FAQ, I'm sharing the script > here. You can do something similar with the session external acl helper, periodically denying access. To do this use the helper in the automatic mode, and have a relatively small session timeout smaller than the ttl specified in external_acl_type. But be warned that some browser automatically retries the cached credentials a couple of times before asking the user to authenticate again. Also, in most browsers it's sufficient to just cancel the login box and try again.. Regards Henrik
