Description Carlos Goncalves 2020-03-14 13:16:10 UTC

HTTP/2 is a new version of the HTTP protocol that brings improved page load performance. Currently, the Octavia API does not support HTTP/2, but version 2.0 or newer of HAProxy supports it.

Note: Versions of HAProxy less than 2.0 had some support for HTTP/2, but it was incomplete and buggy.
