Temporarily suspend cache additions.

Stops more data being added to the cache, but still allows cache retrieval. This is useful for actions, such as imports, when a lot of data would otherwise be almost uselessly added to the cache. Suspension lasts for a single page load at most. Remember to call this function again if you wish to re-enable cache adds earlier.


$bool = wp_suspend_cache_addition( $suspend );


( bool ) optional – Optional. Suspends additions if true, re-enables them if false.


bool The current suspend setting
