HTTP/2 is a major revision of HTTP network protocol used by WWW (World Wide Web). It was derived from SPDY protocol (developed by Google). HTTP/2 is supported by almost all modern browsers.
cPanel has recently added support for HTTP/2 in EasyApache 4. Now, cPanel users can enable HTTP/2 on their server. HTTP/2 can boost website speed loading and there are other advantages as well.
