[squid-users] More access.log questions

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.

Thanks in advanced.
