HTTP/2 and You

HTTP/2 and You

You may have missed it; the biggest update to the HTTP protocol in over 15 years was finalized this year. The long awaited HTTP/2 update is finally here and you can take advantage of it now, but what does this change mean for you, a builder of the web? In my talk, I will break down the important aspects of the new HTTP/2 protocol, how it differs from HTTP/1.1, and ways in which you can take advantage of the HTTP/2 performance improvements today. Whether you realize it or not, HTTP/2 will affect your life in the near future and I will help you understand what it all means.
