Hi Hugo,
The flags you mention are per transaction flags and they are visible as
time the route is in a transaction context. Unfortunately you came
across the only exception. You are using the generic "onreply_route"
where there is no transaction contect (openser has no idea -yet- about
the transaction the reply belongs to). A reply route with transaction
context is onreply_route[x] - this is set per transaction by t_on_reply().
Regards,
Bogdan
