Yes, the CDN caching level can be set to these levels:
No Query String: Only delivers files from cache when there is no query string.
Ignore Query String: Delivers the same resource to everyone independent of the query string.
Standard: Delivers a different resource each time the query string changes.
We recommend the Standard level. Learn more
By default, our CDN does not cache HTML content.
Please open a support ticket to request the caching level to be changed or to enable HTML caching.
