Available in: 2.6

For older versions than 3.3 see the linked pages above
Location for the cache "swap.state" file. This log file holds the metadata of objects saved on disk. It is used to rebuild the cache during startup. Normally this file resides in each 'cache_dir' directory, but you may specify an alternate pathname here. Note you must give a full filename, not just a directory. Since this is the index for the whole object list you CANNOT periodically rotate it! If %s can be used in the file name it will be replaced with a a representation of the cache_dir name where each / is replaced with '.'. This is needed to allow adding/removing cache_dir lines when cache_swap_log is being used. If have more than one 'cache_dir', and %s is not used in the name these swap logs will have names such as: cache_swap_log.00 cache_swap_log.01 cache_swap_log.02 The numbered extension (which is added automatically) corresponds to the order of the 'cache_dir' lines in this configuration file. If you change the order of the 'cache_dir' lines in this file, these log files will NOT correspond to the correct 'cache_dir' entry (unless you manually rename them). We recommend you do NOT use this option. It is better to keep these log files in each 'cache_dir' directory.
