Client sites will be moving to CDN starting April 2015 through June 2015.
Encompass client websites go through a Content Delivery Network (CDN) hosted by EdgeCast. iModules uses their Transact CDN product which allows all SSL pages including Login, Commerce and Admin pages to be on the CDN.
Currently we only cache the following file types on the Transact CDN:
Purging files on CDN
Once a file is cached in the CDN is is cached indefinitely unless a purge request is sent.
Purge requests are sent automatically to EdgeCast every time a file is added/replaced/uploaded in Encompass. These requests are added to a queue and then purged by Edgecast every minute.
Even though the purge requests are processed every minute of the day, due to the nature of the CDN it could take up to five minutes before a client may see the correct/new image.
Forcing purge requests
Files added via FTP or any other method not within the Encompass UI will require a manual purge request to be sent to EdgeCast. Please contact Application Support for assistance.
