Cache::AgainstFile::Storable - cache data structures parsed from files in
my $cache = new Cache::AgainstFile(
Method => 'Storable',
CacheDir => '/var/tmp/cache/myapp',
$data = $cache->get($filename);
Data structures parsed from files are cached in "shadow" storable
files. If parsing is significantly more expensive than file I/O (e.g. with XML
files), then this will offer some benefit.
This backend is suitable for non-persistent environments (e.g. CGI
scripts) where you want the cache to outlive the process. For persistent
environments, the Memory backend may be more suitable as it saves on file
count() and size() are relatively expensive
operations involving scanning the cache directory.
- Directory in which to store cache files. This is mandatory.
- Purge items older than this. Value is in seconds
- Purge oldest items from the cache to reduce the number of items in the
cache to be at most this number. Value should be an integer
- Don't stat files to validate the cache - items are served from the cache
until they are purged. Valid values are 0|1 (default=0, i.e. files are
- Valid values are Flock and AtomicWrite (default is AtomicWrite). If
neither of these are to your taste, consider using
Cache::AgainstFile::CacheModule with another caching module. Some other
file caching modules on CPAN are:

- This uses atomic writes.
- This uses File::NFSLock for locking (no locking is also an option)
