\$cache\_id {#variable.cache.id}
|
||
|
|
===========
|
||
|
|
|
||
|
|
Persistent cache\_id identifier. As an alternative to passing the same
|
||
|
|
`$cache_id` to each and every function call, you can set this
|
||
|
|
`$cache_id` and it will be used implicitly thereafter.
|
||
|
|
|
||
|
|
With a `$cache_id` you can have multiple cache files for a single call
|
||
|
|
to [`display()`](#api.display) or [`fetch()`](#api.fetch) depending for
|
||
|
|
example from different content of the same template. See the [caching
|
||
|
|
section](#caching) for more information.
