https://forum.netgate.com/topic/118255/squid-reverse-proxy-switching-peers:
I want Squid to direct incoming requests to a specific peer based on URI, but what I'm getting instead is it's sending the requests to each peer in a round-robin fashion. So, once in a while, I get the content, or sometimes I get a 404 when it's hitting the wrong peer. I only have one peer selected per mapping.
...
I have a working solution that might have to be re-implemented if and when I update the squid package. The trick is to add cache_peer_access directives that specifically deny the peers from the other mappings. For some reason, the "deny allsrc" that is automatically generated is not cutting it.
