Web pages, dynamic or not, are resource intensive. Browsers typically open one or more TCP connections to an infrastructure to request resources. This motivated the Internet Engineering Task Force (IETF) to pursue a new protocol focused on network performance. In the process, other improvements were adopted. HTTP/2 is the latest generation of HTTP protocols. The main body of the new protocol was influenced and based on Google-sponsored SPDY.
HTTP/2 has several advantages over HTTP:
Using the protocol and these features can reduce response time for websites.
Acquia supports HTTP/2 on its platform, with some exceptions. If you have a compliant HTTP/2 client, no configuration is required.
Acquia’s HTTP/2 implementation doesn’t support the following features:
If your website is behind a CDN which supports HTTP/2, such as Acquia Cloud Edge, it has HTTP/2 support. If your website is behind a CDN that doesn’t support HTTP/2, you won’t.
