Cron API: Make wp-cron non-blocking for LiteSpeed LSAPI.

peterwilsoncc · peterwilsoncc · commit 1ff92618f22b · 2022-07-05T03:12:36.000Z
This should make cron spawning faster on LSAPI by ensuring that cron requests return immediately. To avoid code repetition, the no caching headers are relocated and always sent. Caching plugins attempting to set these headers later will replace those set by WordPress Core. Follow up to [44488]. Props maximej, johnbillion. Fixes #54668. git-svn-id: https://develop.svn.wordpress.org/trunk@53653 602fd350-edb4-49c9-b593-d223f7449a82
