never_direct and allow_direct are lists with multiple lines performing
if-else logic just like http_access.

Think about it like this: you said you want these clients to go direct
*sometimes*, so why are you setting them to *never* go direct? ("all"
matches everything).

prefer_direct determins whether the parent or DIRECT are *tried* first.
First route to succeed suplies the answer.
