## CacheSize

Syntax: CacheSize <size>
Default: `CacheSize 5`
Context: server config, virtual host
Override: Not applicable
Status: Base
Module: mod_proxy
Compatibility: CacheSize is only available in Apache 1.1 and later.

Sets the desired space usage of the cache, in KB (1024-byte units). Although usage may grow above this setting, the garbage collection will delete files until the usage is at or below this setting.
Depending on the expected proxy traffic volume and `CacheGcInterval`, use a value which is at least 20 to 40 % lower than the available space.
