This is a must-read for any web developer, frontend, or backend, or full-stack. It's short enough to be a fun read, but detailed enough to convey the most important browser networking facts. If you can, buy a hard copy to keep as a reference. I have referred back to mine regularly (and will surely refer back to it in the future, likely next time I have to do something serious with websockets). It's fairly neatly organized by protocol, so if you just need a quick review of HTTP2 (for example), you can skip to that section and read it in isolation. I highly, highly recommend.
