### Versioned cache segmentation
|
||||||
|
|
||||||
|
`SS_Cache` segments caches based on the versioned reading mode. This prevents developers
|
||||||
|
from caching draft data and then accidentally exposing it on the live stage without potentially
|
||||||
|
required authorisation checks. This segmentation is automatic for all caches generated using
|
||||||
|
`SS_Cache::factory` method.
|
||||||
|
|
||||||
|
Data that is not content sensitive can be cached across stages by simply opting out of the
|
||||||
|
segmented cache with the `disable-segmentation` argument.
|
||||||
|
|
||||||
|
```php
|
||||||
|
$cache = SS_Cache::factory('myapp', 'Output', array('disable-segmentation' => true));
|
||||||
|
```
