46 * Available options
47 *
48 * =====> (string) cache_dir :
49 * - Directory where to put the cache files
50 *
51 * =====> (boolean) file_locking :
52 * - Enable / disable file_locking
53 * - Can avoid cache corruption under bad circumstances but it doesn't work on multithread
54 * webservers and on NFS filesystems for example
55 *
56 * =====> (boolean) read_control :
57 * - Enable / disable read control
58 * - If enabled, a control key is embeded in cache file and this key is compared with the one
59 * calculated after the reading.
60 *
61 * =====> (string) read_control_type :
62 * - Type of read control (only if read control is enabled). Available values are :
63 * 'md5' for a md5 hash control (best but slowest)
64 * 'crc32' for a crc32 hash control (lightly less safe but faster, better choice)
65 * 'adler32' for an adler32 hash control (excellent choice too, faster than crc32)
66 * 'strlen' for a length only test (fastest)
67 *
68 * =====> (int) hashed_directory_level :
69 * - Hashed directory level
70 * - Set the hashed directory structure level. 0 means "no hashed directory
71 * structure", 1 means "one level of directory", 2 means "two levels"...
72 * This option can speed up the cache only when you have many thousands of
73 * cache file. Only specific benchs can help you to choose the perfect value
74 * for you. Maybe, 1 or 2 is a good start.
75 *
76 * =====> (int) hashed_directory_umask :
77 * - deprecated
78 * - Permissions for hashed directory structure
79 *
80 * =====> (int) hashed_directory_perm :
81 * - Permissions for hashed directory structure
82 *
83 * =====> (string) file_name_prefix :
84 * - prefix for cache files
85 * - be really carefull with this option because a too generic value in a system cache dir
86 * (like /tmp) can cause disasters when cleaning the cache
87 *
88 * =====> (int) cache_file_umask :
89 * - deprecated
90 * - Permissions for cache files
91 *
92 * =====> (int) cache_file_perm :
93 * - Permissions for cache files
94 *
95 * =====> (int) metatadatas_array_max_size :
96 * - max size for the metadatas array (don't change this value unless you
97 * know what you are doing)
