Its now cache_swap_state to better reflect the file to which it applies, and that the file is NOT a normal log file. 2) Better leave the cache_swap_log/cache_swap_state at defaults (missing from squid.conf) for squid to handle it safely. 3) What Adrian meant was the order of the lines in squid.conf. Not an actual re-ordering of cache-dir. This is a major reason for #2, so a re-ordering in the config does not screw up the custom state file numbering.
