my.policy URI rename

It is by design and no way to change that in the configuration. That said, you could technically rewrite it. This is untested, but should work:

when CLIENT_ACCEPTED {
    ACCESS::restrict_irule_events disable
}
when HTTP_REQUEST {
    if { [HTTP::uri] starts_with "/login" } {
        HTTP::uri [string map {"/login" "/my.policy"} [HTTP::uri]]
    }
}
when HTTP_RESPONSE {
    if { ( [HTTP::is_redirect] ) and ( [HTTP::header Location] starts_with "/my.policy" ) } {
        HTTP::header replace Location [string map {"/my.policy" "/login"} [HTTP::header Location]]
    }
}
