n HTTP/2 we hope to see http2 support soon get added to popular

server implementations such as the Apache HTTP Server and nginx. H2O is a new blazingly fast HTTP server with http2 support that shows potential.

So in the HTTP/2 era, we may see H2O as a new rising star,

next to the proven webservers like Nginx and Apache.
