Is HTTP/2 worth the performance price of TLS?
HTTP/2 (h2) is incredibly exciting: The first major rev to HTTP in 15 years, focused on modern web development, performance minded, etc., etc. But one thing that has people looking at it with trepidation is that to use it you effectively need to move your site over to TLS (i.e. HTTPS). Though not a requirements in the protocol, no major browser has plans to put h2 in the clear. Whether you think this is a good thing or a bad thing ( I personally am thrilled ) it brings front and center the questions you may have been avoiding: should I move my site to TLS?
