[squid-users] Lots of "Vary object loop!"

[Sebastian Goicochea]

Hello everyone, I'm having a strange problem:

Several servers, same hardware, using same version of squid (3.5.4) 
compiled using the same configure options, same configuration files. But 
in two of them I get LOTS of these Vary object loop! lines in cache.log

I've read what I could find on forums but could not solve it. Is this 
something to worry about? If that is not the case, how can I disable the 
excessive logging?
Which is the condition that generates this?


Thanks,
Sebastián
