You could use this:

proxy_cache_key $scheme$remote_addr$host$$server_port$request_uri;

This would make originating IP addresses ($remote_addr) part of
the cache key, so different clients would get the correct responses
from the cache just as if they were accessing the backend directly,
there's no need to bypass the cache at all.
