I Love W3TC, but have a need to be able to purge the cache as a step in an existing (shell) Cron job. The cron job will run as long as is necessary and will have an irregular completion time. Therefore I would like to make it a step in the cron job.
I essence, I have pages that are static for ~24hours until a cronjob updates a product database, after which I would like to have the cron job make a call to flush the entire W3TC cache such that the updated pages are served until next day (or any other changes are made).
Is this possible?
