[squid-users] TCP_DENIED:NONE and Forwarding loop

Hi All,

I am having a problem with our Squid hierarchy. I am getting
TCP_DENIED in the access.log and the cache.log shows a forwarding
loop detected. Here is the access.log entry:

192.168.1.81 - - [03/Sep/2007:14:01:06 -0500] "GET http://
web.example.com/customers/mba HTTP/1.0" 403 1469 TCP_DENIED:NONE
208.106.5.39 - - [03/Sep/2007:14:01:06 -0500] "GET http://
web.example.com/customers/mba HTTP/1.1" 403 1570 TCP_MISS:DIRECT

And here is the cache.log entries:

2007/09/03 13:58:50| parseHttpRequest: NF getsockopt(SO_ORIGINAL_DST)

2007/09/03 14:00:20| parseHttpRequest: NF getsockopt(SO_ORIGINAL_DST)

I think our Squid parent is not responding so Squid goes direct to
source. Is there a way to ensure that Squid will not go to origin
even if the parent does not respond? We do DNS load-balancing so
when the Squid tries to go direct to source, I think that is where
our loop begins.

Thanks,
Paul
