[squid-users] Cache Log errors

Can anyone explain if these are important messages. My squid server
appears to be working but im concerned:

The 51.63.xx.xx and 192.168.xx.xx are peers. I am able to access the
particular website via these peers but I receive the messages below.

If there is any other information I can provide to investigate please
say so, but also please suggest the commands I should use, as my
knowledge is brief.
