How can I prevent the internal stuff from being forwarded to the
parent_proxy?
Hello Hildebrand,
A forwarding loop is when a request passes through one proxy more than
once. You can get a forwarding loop if
* a cache forwards requests to itself. This might happen with
interception caching (or server acceleration) configurations.
* a pair or group of caches forward requests to each other. This can
happen when Squid uses ICP, Cache Digests, or the ICMP RTT
database to select a next-hop cache.
