Question
How do I enable HTTP/2 with the use of LiteSpeed?
Answer
You can enable HTTP/2 by going to your LS Web Console.
In the WebAdmin Console, you can find the Enable SPDY/HTTP2/HTTP3 option in the SSL tab for both Listeners and Virtual Hosts. Select the HTTP/2 option to enable HTTP/2.
There is also a method to perform this through the command line as well. LiteSpeed Documentation for HTTP/2 will have more details about that method and how to verify the information.
