Re: [squid-users] About log file record

The one you have.

What happens is

1. ICP times out

2. never_direct (or prefer_direct off) tells Squid it still needs to find a
parent

3. Squid goes throught the different normal parent selection methods it has
but did not find any good parent to use

4. You are using never_direct, so Squid simply tries to use any of it's
parents even if none looked too good. Trying is better than rejecting the
request.

The ICP_TIMEOUT_ part is indeed a problem and should be addressed. As you do
not seem to actually use ICP or need it, specify the no-query option on the
cache_peer line to disable the use of ICP to this peer.

The ANY_PARENT part is not a problem. It is only telling you that despite the
fact that ICP failed, Squid ended up doing what you intended.

Henrik
