There was a problem hiding this comment.
Conditional per-worker cache_dir directives are not supported by the Squid Project. The exact effects of using such directives depend on Squid version. They may include stale cache entries and crashes. Squid does not refuse to start with such configurations (for now), but YMMV.
It would be nice if this example warned readers that they are looking at a dangerous and unsupported hack (rather than some new/experimental feature that should already work OK in many cases and will get better with time).
