cache.log entries

 Hello, All!
I have squid2.2.S3 on Debian Linux 2.1
In cache.log I have a lot of entries like this:

1999/06/16 12:23:34| clientKeepaliveNextRequest: FD 18 Sending next

and

1999/06/16 12:42:33| clientSendMoreData: Deferring
http://http.us.debian.org/debian/dists/unstable/main/binary-i386/Release

Could anyone explain me what does it mean?
