8.4. Disk-Based Storage

The mod_disk_cache module is a disk-based storage manager for mod_cache. It implements the cache type disk.

Responses are stored in files in a cache directory tree, which is created based on hashes of the cached URLs. The cache is structured as a hierarchy of directories to reduce the number of files in each directory and so reduce the time taken for directory searches. The size of the cache can be managed with the htcacheclean program.
