APM portal - user bookmarks to /my.policy - any way to redirect?

You could try something like this:

when CLIENT_ACCEPTED {
     Allow access to APM specific pages (this may not be necessary for the my.policy page)
    ACCESS::restrict_irule_events disable
}

when HTTP_REQUEST {
    if { [HTTP::uri] equals "/my.policy" } {
        log local0. "Path: my.policy"
        log local0. "  Access: '[ACCESS::policy result]'"

        if { [ACCESS::policy result] equals "" } {
            log local0. "  Invalid request (user bookmark?)"

             Redirect to the desired uri
            HTTP::respond 302 Location "/"
            return
        }
    }
}

If the user comes to the

my.policy
