[squid-users] How can I turn off TCP_DENIED/403 and 407 logging?

 I use squid since 1.1. Now it 2.6s17, on linux, of course!

 Since 1.1, squid always runs in Proxy_Authen mode.

 Now the 2.6s17 serves about 1,200 clients . There's new clients,
around 100 every month (the old one just fade away). All clients (and
software) have to log in to Squid Proxy before able to surf (via
basic auth: ncsa).

 Problem is that: While most ppl read the documents, follow instructions,
etc, etc, some are NOT. Some even careless ... install software they
don't use, or let rogue softwares install themself !

 So, both the people and softwares try to access the new without login.

 Result ?

 My access.log size is 400-1,200 MB everyday (yes, I rotate it
everyday at 23:55pm)
 Worse, 3/4 of access.log is just TCP_DENIED/403 and TCP_DENIED/407.

 I have to pipe it to grep -v after every rotation. But ... wrote 3/4
gigabyte of useless information slow down squid somewhat.

 QUESTION: How can I turn off these two messages? It's useless ..

 BTW, I had tried my best to search through _that_ dreadfull /src/*.c
and try making some changes. Useless. (In fact , I'm just a half-noob
in VB). Try searching/reading 4 years of usenet. No answer. Google
ignores me completely ...

 Thanks in advance.
