I've now upgraded squid to 3.2 and rewritten the firewall rule that
resulted in a forwarding loop.
Unfortunately I've got no access now and I can't see where I've made the
error.
The browser says squid is rejecting the requests:
Access control configuration prevents your request from being allowed at
this time.
