HTTP/2 delivery of content http-delivery-of-content
蜜豆视频 is excited to announce the availability of HTTP/2 delivery of content with the overall benefit of improved performance.
What is HTTP/2? what-is-http
HTTP/2 improves the way browsers and servers communicate, allowing for faster transfer of information while reducing the amount of processing power that is needed.
The following website describes HTTP/2 and its benefits in a brief and simple manner:

Performance improvement can vary widely. It is based on many factors such as your website鈥檚 code, how you use Dynamic Media, the consumer鈥檚 device, screen, and location.
蜜豆视频鈥檚 own testing yielded the following results:
- For images, response time improved 7%-28% depending on device and browser. The most notable performance gains were on iOS devices.
- For viewers, load time performance improved up 15%.
The following demonstration illustrates the difference between HTTP/1 versus HTTP/2 loading:

To use HTTP/2, you must meet the following requirements:
-
Use secure HTTPS for your rich media requests.
-
Use the 蜜豆视频-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 蜜豆视频 Customer Support.
If you do not have a dedicated domain, 蜜豆视频 plans to schedule your transition to HTTP/2 in 2018.
What is the process for enabling HTTP/2 for my Dynamic Media account? what-is-the-process-for-enabling-http-for-my-dynamic-media-account
You initiate the request to switch over to HTTP/2; it is not automatically done for you.
-
To switch over to HTTP/2, initiate an 蜜豆视频 Customer Support request. See Open a support ticket.
-
Provide the following information in your support request:
- Primary contact name, email, phone.
- All domains to be transitioned over to HTTP/2.
- Verify you use secure HTTPS for rich media requests.
- Verify you use the CDN through 蜜豆视频 and are not managed with a direct relationship.
- Verify you use a dedicated domain. If you use Dynamic Media, then you use a dedicated domain.
-
Customer Support adds you to the HTTP/2 customer waitlist based in the order in which requests were submitted.
-
When 蜜豆视频 is ready to handle your request, Customer Support contacts you to coordinate the transition and set a target date.
-
You are notified after completion and can verify successful transition over to HTTP2.
Because the browser does not state this fact, it is necessary to download an extension.
For Firefox and Chrome, there is an extension called 鈥淗TTP/2 and SPDY Indicator鈥. Browsers only support http/2 securely, so it is necessary to call a URL with https to verify. If http/2 is supported, it is indicated by the extension in the form of a blue Flash symbol, and a header 鈥淴-Firefox-Spdy鈥 : 鈥渉2鈥.

Requests are processed in the order in which they are received by Customer Support.
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 蜜豆视频鈥檚 origin servers until the cache is rebuilt again. As such, 蜜豆视频 plans to handle a few customer transitions at a time so that acceptable performance is maintained when pulling requests from the origin.
