The CacheEnable directive instructs mod_cache to cache urls at or below url-string. The cache store is specified with the cache_type argument. cache_type mem instructs mod_cache to use the in-memory cache storage manager implemented by mod_mem_cache. cache_type disk instructs mod_cache to use the cache storage manager implemented by mod_disk_cache.

The CacheDisable directive instructs mod_cache to not cache urls at or below url-string.

The maximum time in seconds to cache a document. The CacheMaxExpire takes precedence over the Expires field from the header.

The default time in seconds to cache a document if the page does not have an expiry date in the Expires field.

Ignore responses where there is no Last Modified Header.

Ignore requests from the client for uncached content

The factor used to estimate the Expires date from the LastModified date.

Percentage of download to arrive for the cache to force complete transfer.

Maximum number of bytes of a streamed response (i.e., a response where the entire content is not available all at once, such as a proxy or CGI response) to buffer before deciding if the response is cacheable. By default, a streamed response will not be cached unless it has a Content-Length header. The reason for this is to avoid using a large amount of memory to buffer a partial response that might end up being too large to fit in the cache anyway. To enable caching of streamed responses, use CacheMaxStreamingBuffer to specify the maximum amount of buffer space to use per request.
