After considerable testing with a site with other 50k posts on it, we have proved that the problem with the Purge Queue is now fixed. It was previously giving errors from CRON.
In addition we also added a new filter to the system to allow for headers to be adapted programmatically.
- Bugfix for purge queue on large sites. It was giving CRON errors.
- Added filter to allow for adaption of headers on Full Page Caching.
