Hello.
Guys, sorry to post so many questions regarding access.log but, I'm
trying to understand what is squid actually doing and if is working
correctly. I don't understand what all the stuff in the access.log file
are. I check the log everyday. I see something different every time I
check. Below is the latest on access.log and I don't understand why the
cache now is "DIRTY", what is assertion failed, 1 swapin MD5
mismatches,
WARNING: newer swaplog entry for dirno 0, fileno 0000013B, and all
those
weird characters at the end of the log:
008.LMP%C2%BB%C2%A6%C2%AB_A.zip?Cache'
Ì«* 2008 14:02:37 GMT}ARNING: suspicious CR characters in HTTP header
{Date: Tue, 16 ð@
Please help me understand what's going on.
Well for starters. The access.log does not contain that kind of info.
That stuff should be in the cache.log with the rest of the debug and
administration information.
The FAQ has a good detailed explanation of what the logs do and
contain...

Thanks in advanced.

2008/12/15 22:06:31| Rebuilding storage in /var/log/squid/cache (DIRTY)
Squid crashed earlier before completing its slow cache validation check.
That caused the swap.state journal to be out of sync with the cache,
corrupt or missing. Turning to paranoid and re-building indexes from a
full raw object scan.
