external_acl helper question

  I'm writing an external_acl helper for a project where we want to make decisions about choosing an outgoing address based on the destination of the connection. I've written a program that will take in an argument (from the acl) and has a %DST format.

  However, in my testing, it's never used. It starts up, because I set children-startup=1, but looking at the log I'm never seeing any of the debugging printf's I put in it that I do see if I run it by hand and feed it data.

  I noticed inside of forward.cc, in getOutgoingAddress, the ACL checking it's doing calls cf->fastCheck(). Does that mean that it will avoid calling "slow" acl mechanisms for some reason? Or am I inferring too much?

  Either way, I wanted to ask, because I can tell that I'm seeing connections and it's trying to choose an outgoing address, but seems to never choose the ones attached to the external_acl helper, and seems to never inquire of it.

  Thanks.
