[squid-users] cache_peer configuration is not being reliably hit in Squid 3.2.1

Hello all,

I'm running Squid 3.2.1, with a cache_peer configured to point at
another local Squid instance as a parent proxy. The parent proxy is
not getting reliably hit, for the *exact* same url.

acl objectcache url_regex -i "/path/to/regexes"

cache_peer localhost parent 60084 0 proxy-only
name=objectcachepeer-peer no-digest no-query
cache_peer_access objectcache-peer allow objectcache
client_dst_passthru off

Example output from access.log:

This issue was also present in 3.2.0.19 and 3.2.0.20. Are there any
configuration options I may be missing? I've had this working before,
in Squid 3.2.0.16 and Squid 3.2.0.17, with the options detailed above.

Thanks,

Nathan.
