6 Cache::FileCache -- implements the Cache interface.
7
9 The FileCache class implements the Cache interface. This cache stores
10 data in the filesystem so that it can be shared between processes.

13 use Cache::FileCache;
14
15 my $cache = new Cache::FileCache( { 'namespace' => 'MyNamespace',
16 'default_expires_in' => 600 } );

18 See Cache::Cache for the usage synopsis.

21 See Cache::Cache for the API documentation.

23 Clear( [$cache_root] )
24 See Cache::Cache, with the optional $cache_root parameter.
25
26 Purge( [$cache_root] )
27 See Cache::Cache, with the optional $cache_root parameter.
28
29 Size( [$cache_root] )
30 See Cache::Cache, with the optional $cache_root parameter.
31
33 See Cache::Cache for standard options. Additionally, options are set
34 by passing in a reference to a hash containing any of the following
35 keys:
36
37 cache_root
38 The location in the filesystem that will hold the root of the
39 cache. Defaults to the 'FileCache' under the OS default temp
40 directory ( often '/tmp' on UNIXes ) unless explicitly set.
41
42 cache_depth
43 The number of subdirectories deep to cache object item. This
44 should be large enough that no cache directory has more than a few
45 hundred objects. Defaults to 3 unless explicitly set.
46
47 directory_umask
48 The directories in the cache on the filesystem should be globally
49 writable to allow for multiple users. While this is a potential
50 security concern, the actual cache entries are written with the
51 user's umask, thus reducing the risk of cache poisoning. If you
52 desire it to only be user writable, set the 'directory_umask'
53 option to '077' or similar. Defaults to '000' unless explicitly
54 set.
55
57 See Cache::Cache for default properties.
