Abstract
Techniques for determining whether HTTP/2 or HTTP/3 is a preferred protocol for communication between a client device and a server over a network are described. A change associated with a network interface of a client device is detected. Based at least in part on detecting the change, a determination is made to identify a preferred communication protocol for a network over which the client device communicates using the network interface. A HTTP/2 probe is transmitted over the network and to a server. A HTTP/3 probe is transmitted over the network and to the server. In response to not receiving a HTTP/3 probe response, the preferred communication protocol is determined to be HTTP/2. In response to receiving the HTTP/2 probe response and the HTTP/3 probe response, the preferred communication protocol is determined to be HTTP/3. The client device communicates with the server over the network using the preferred communication protocol.
