# Caching
|
||
|
|
|
||
|
|
## Built-In Caches
|
||
|
|
|
||
|
|
The framework uses caches to store infrequently changing values.
|
||
|
|
By default, the storage mechanism is simply the filesystem, although
|
||
|
|
other cache backends can be configured. All caches use the `[api:SS_Cache]` API.
|
||
|
|
|
||
|
|
The most common caches are manifests of various resources:
|
||
|
|
|
||
|
|
* PHP class locations (`[api:SS_ClassManifest]`)
|
||
|
|
* Template file locations and compiled templates (`[api:SS_TemplateManifest]`)
|
||
|
|
* Configuration settings from YAML files (`[api:SS_ConfigManifest]`)
|
||
|
|
* Language files (`[api:i18n]`)
|
||
|
|
|
||
|
|
Flushing the various manifests is performed through a GET
|
||
|
|
parameter (`flush=1`). Since this action requires more server resources than normal requests,
|
||
|
|
executing the action is limited to the following cases when performed via a web request:
|
||
|
|
|
||
|
|
* The [environment](/topics/environment-management) is in "dev mode"
|
||
|
|
* A user is logged in with ADMIN permissions
|
||
|
|
* An error occurs during startup
|
||
|
|
|
||
|
