Encompass client websites go through a Content Delivery Network (CDN) hosted by Cloudflare. iModules uses their Enterprise Website product which allows all SSL pages including Login, Commerce and Admin pages to be on the CDN.
Currently we cache the following file types on Cloudflare usinge their Standard level of caching:
The Standard level of caching delivers a different resource every time the query string changes.
Purging files on CDN
Once a file is cached in the CDN is cached indefinitely unless a purge request is sent.
Purge requests are sent automatically to Cloudflare every time a file is added/replaced/uploaded in Encompass. Even though the purge requests are processed when Cloudflare receives them, due to the nature of the CDN it could take up to five minutes before a client may see the correct/new image/file.
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 Cloudflare. Please contact Customer Support for assistance.
