It might be simpler to just add a "condition" (or two) to the autoreply router pointing to the autoreply transport.

You can use Redis, and use the INCR command and check for a value greater than one, meaning the key was there before.

The second condition can be used to EXPIRE the key. If the previous condition failed, this would not execute. If the previous condition passed, that means the key was just added to redis and needs a TTL set. This condition can be forced to always return 1 or whatever.
