# Cache / SetCacheViewHelper {#viewhelper-set-cache}

This is a ViewHelper to set a new cache entry.

## General properties {#viewhelper-set-properties}

-   **prefix**

    -   *Type:* string

    If you want you can define a prefix for the generated CacheIdentifier. Leave
    this value empty to use "infoWindow" as default value

-   **poiCollection**

    -   *Type:* PoiCollection
    -   *Required:* true

    You must assign the PoiCollection object to this ViewHelper. We extract some
    data from PoiCollection to build a more unique CacheIdentifier which can differ
    Caches in multilingual environment.

    two additional Cache Tags named `infoWindowUid{PoiCollectionUid}` and
    `infoWindowPid{PoiCollectionPid}`

-   **lifetime**

    -   *Type:* int

    How long (in seconds) the CacheEntry should be available, before it will be
    re-generated? Keep this value empty to use the Default Value of Storage-Backend.
