Hi, I can see quite a few of these entries in my cache.log: 2013/01/14 08:20:23 kid1| Failed to select source for '[null_entry]' 2013/01/14 08:20:23 kid1| always_direct = 0 2013/01/14 08:20:23 kid1| never_direct = 0 2013/01/14 08:20:23 kid1| timedout = 0 What could be generating these entries? I started seeing them after an upgrade from 3.1.6 (debian build) to 3.2.6 (from sources). Maybe they just weren't logged in the previous version, but where do they come from? Look like requests with an empty Host header. Regards, Tuukka
