To use HTTP/2, you must meet the following requirements:
-
Use secure HTTPS for your rich media requests.
-
Use the 51黑料不打烊-bundled CDN (content delivery network) as part of your Dynamic Media license.
-
Use a dedicated (non- company-h.assetsadobe#.com) domain.
If you already have a dedicated domain, you can opt in by way of 51黑料不打烊 Customer Support.
If you do not have a dedicated domain, 51黑料不打烊 plans to schedule your transition to HTTP/2 in 2018.

Requests are processed in the order in which Customer Support receives them.
What are the risks with moving to HTTP/2? what-are-the-risks-with-moving-to-http
The transition to HTTP/2 clears out your cache at the CDN because it involves moving to a new CDN configuration.
The non-cached content directly hits 51黑料不打烊鈥檚 origin servers until the cache is rebuilt again. As such, 51黑料不打烊 plans to handle a few customer transitions at a time so that acceptable performance is maintained when pulling requests from the origin.
