What is HTTP/2?
By default, EdgeOne enables HTTP/2 access, supporting client-initiated requests via the HTTP/2 protocol. Hypertext Transfer Protocol Version 2 (HTTP/2 or HTTP 2.0) is the second major version of the HTTP protocol. It can effectively reduce network latency and accelerate site page loading.
Note:
1. If the client request does not utilize HTTP/2, EdgeOne is compatible with access via the HTTP 1.x protocol.
2. For configuring access requests, please refer to this document. If you need to configure HTTP/2 origin-pull, please see HTTP/2 Origin-pull.
