What does that look like to you?

I see your squid receiving a request and deciding to send it back to
itself again. You very urgently need to find out why that is happening and
stop it.

Common causes are:
 - transparent interception. Configured to catch _everything_ exiting the
LAN, failing to exempt squid box.

 - peering with a domain named peer. Domain name pointing at multiple IP,
including local squid box IP.

 - multiple interface on the local squid box. Peering with self on other
interface.

Your squid should by default be detecting such looping and aborting the
requests after the second return. You have a secondary issue as to why
your squid lets it get longer than "X-Forwarded-For: 10.1.21.10,
192.168.1.93, 192.168.1.93,".
