ctx cache.log entries

Hi All,

I'm running Squid-2.HEAD-20071216 on one of my boxes for testing
purposes... overall I'm seeing better performance compared to
2.6STABLE17; however, my cache.log now contains a lot of entries like
the following:

2007/12/17 13:17:58| ctx: enter level 0:
'http://ws.audioscrobbler.com/1.0/user/gatchan82/weeklyartistchart.xml?images=true&widget=1&limit=15'
2007/12/17 13:17:58| storeSetPublicKey: unable to determine vary_id for
'http://ws.audioscrobbler.com/1.0/user/gatchan82/weeklyartistchart.xml?images=true&wi
dget=1&limit=15'
2007/12/17 13:18:14| ctx: exit level 0

Any ideas whether this is a configuration issue (squid.conf below my
sig), or a bug?

Thanks
