disabling TIMEOUT_FIRST_PARENT_MISS functionality

Just a quicky. Is anyone aware of whether it's possible to not use a parent
cache to retrieve an object if no response is heard from them (ie, such that
you'd never have a "TIMEOUT_FIRST_PARENT_MISS" entry in the access.log).
This is in a situation where the ICMP stuff isn't being used, too, so
relying on CLOSEST_PARENT_MISS isn't an option.

Anyone needed to create this functionality? Any patches, perhaps? I'd like
get squid working on the basis that if no response is heard from a parent
cache, then none of the parent caches are going to be in a state to handle a
fetch ...

If no-one has, then I'll start to hack at the source, but I just wanted to
check first ...

Cheers,

Chris
