CacheDirLength 指令
| 说明 | The number of characters in subdirectory names |
|---|---|
| 语法 | CacheDirLength length |
| 默认值 | CacheDirLength 2 |
| 作用域 | server config, virtual host |

| 模块 | mod_disk_cache |
CacheDirLevels directive sets the number of subdirectory levels in the cache. Cached data will be saved this many directory levels below the CacheRoot directory.
The result of CacheDirLevels* CacheDirLength must not be higher than 20.

|---|---|
| 语法 | CacheMaxFileSize bytes |
| 默认值 | CacheMaxFileSize 1000000 |
| 作用域 | server config, virtual host |

CacheRoot 指令
| 说明 | The directory root under which cache files are stored |
|---|---|
| 语法 | CacheRoot directory |
| 作用域 | server config, virtual host |
| 状态 | 扩展(E) |

CacheRoot directive defines the name of the directory on the disk to contain cache files. If the mod_disk_cache module has been loaded or compiled in to the Apache server, this directive must be defined. Failing to provide a value for CacheRoot will result in a configuration file processing error. The CacheDirLevels和CacheDirLength directives define the structure of the directories under the specified root directory.
