Is there a way to force an XMLHttpRequest to use HTTP/1.1?
问题 I have a server endpoint that supports both HTTP/1.1 and HTTP2. For testing purposes, I want to try downloading content from the endpoint with both HTTP/1.1 and HTTP2 connections, possibly at the same time. When I request data from the endpoint with an XMLHttpRequest, it automatically uses HTTP2, without me including the Connection: Upgrade header. Is there a way to force an XMLHttpRequest to use HTTP/1.1 for the underlying TCP connection? What about other protocols, such as Quic or SPDY? 回答1
