# weglot\_get\_slugs\_cache\_duration

Translated URL slugs are cached in a transient. By default the duration is `0` (no explicit expiration set on the transient). Use this filter to set a custom cache duration, in seconds.

```php
add_filter( 'weglot_get_slugs_cache_duration', 'custom_weglot_get_slugs_cache_duration' );
function custom_weglot_get_slugs_cache_duration( $duration ) {
    return HOUR_IN_SECONDS;
}
```
