Hi,
I'm trying to understand the following behavior I'm seeing with Squid
running in accelerator mode. In short, I'm seeing some TCP_MISS for
requests to a static javascript file which is initially cached and
returned as a cache hit. I suspect the missed cache hits are due to the
cache size being too small and the file eventually getting evicted.
However, I'm confused about what I'm seeing in the Squid access log. For
some of the cache misses I can see in the access log that Squid fetches
the file from the configured origin server but for a vast majority of
them I see HIER_NONE even though Squid is actually returning the file.
Under what situations would Squid fetch content from the origin server
during a cache miss but print HIER_NONE?
It may happen if you have content adaptation (ICAP/eCAP) providing a
response instead of either cache or origin server.
Maybe also if the collapsed forwarding feature is in use. AFAIK, we have
not got the log entries quite right there yet.
