abnormal increase in size of access.log(squid)

[sacthivel.C]

Dear all,
We are using RHL 9.0 as proxy server.
Recently we found that the size of the squid log files starts increasing abnormally.
I am rotating the Log files every week.

Is their any settings to change the abnormal increse in size of squid log files?
Is it possible to stop the "access denied" log to get registerd into the access.log?

Regards,

- First, I suggest you to re-check that
logrotation works as supposed.

- you can tune squid log level using "debug_options" (http://www.visolve.com/squid/squid24s1/logfiles.php, for example)

- I suggest you to analyze proxy log with calamaris http://cord.de/tools/squid/calamaris/ or other tool[s]

HAi,
As per your advice i checked the access.log file.
It contains lots of TCP_DENIED/407 error for 3 ip addresses in our network.

What is this error meant for?
I searched in google.But i didn't find any proper solution?

Would you help me?

It seems like you request user authentication, but some users cannot provide right password; see this for example:

"If it's TCP_DENIED/407 then your proxy is set up to use some form of authentication and the authentication is failing. Either an automated update tool doesn't have the credentials to use or a user has forgotten their username/password. This is usually solved when the user tells you they can't access the internet, or their auto-update is failing."
