A OpenLiteSpeed Web Server is running on AlmaLinux 8.
HTTP/1.1, HTTP/2 and HTTP/3 QUIC are enabled.
80/tcp, 443/tcp and 443/udp ports are open publicly and permanently.
The server is sending the below alt-svc
header:
h3=":443"; ma=2592000, h3-29=":443"; ma=2592000, h3-Q050=":443"; ma=2592000, h3-Q046=":443"; ma=2592000, h3-Q043=":443"; ma=2592000, quic=":443"; ma=2592000; v="43,46"
The setup has been tested positive by http3check succcessfully.
But the user agents, I mean, browsers are connecting through HTTP/1.1 most of the times. HTTP/2 are used by them sometimes. Usage of HTTP/3 is mere.
What should be done to tell the browsers to prefer later versions of HTTP?
