Is there a way to get Discourse to regularly re-cook HTML in posts?
I’ve noticed that a lot of thumbnail previews become broken after a while. Many sites use hashes in image URLs, so when remote sites rebuild the sites or edit images, the hashes change, breaking the previews in Discourse.
There are 230,000+ posts in the forum, so rebuilding them all at once regularly is server-intensive. Ideally it could be done on a regular schedule in a background task.
