<br>
Internally generated requests do not create TM transactions that are accessible from route script. <br>
<br>
What is your actual goal? To change the timeout for non-response to the OPTIONS keepalives? If so, that should probably be added as a modparam. In that case, fr_timer isn't quite the language in which to speak of it, as that makes it sound like a transaction to which you have access in script (with the implication that its failure can trigger a failure_route callback of your own making). That's not the case here. <br>
