During discussions with the YUDU Support Team or just generally on the internet you may have encountered the term 'purge' or 'purging content' - what is this?
In the YUDU context of purging content, when a digital publication is published live, the content is sent to multiple servers around the globe. When a user requests to read the content, the files are then copied to a server location local to the reader.
If you decide to update and republish your content, YUDU Publisher will send the updated version to the servers. However, very rarely, old content is cached and isn't removed immediately (sometimes this is local to the end user's device) and therefore your readers will see the old version.
In order to remove the old content, the servers must be 'purged', deleting the previous version and replacing with the newly updated publication.
Should you experience this with a YUDU digital edition, please contact the Support Team and we will investigate for you. In most instances, we can simply send a manual command to clear the cache.
If the experience is with a self-hosted publication, please consult your own Network/Website Administrators for further information.
