Server Push Thru Http2


Server: nginx-1.15.8 downloaded as Pre-Built Packages from http://nginx.org/en/download.html

Config: in /etc/nginx, different from nginx-1.9.15, whose config in /usr/local/nginx
Add to server section: listen 444 ssl http2;
Add to location section: http2_push /style.css;

Test:
with Chrome: go to https://riowing.net:444/index.htm
Developer Tools – network: header colum shows h2
with Curl 7.63: curl.exe -vso /dev/null –http2 https://riowing.net:444/index.htm
watch for output: “server accepted to use h2”
Notes: style.css is downloaded both with and without http2. The difference is that without a separate corresponding request from browser, or so called Server Push.

Server Push


There are two kinds of server pushes.

1. video server keeps pushing jpg image frames as a way for browser to play video.

AKA M-JPEG over HTTP, “server push stream”. As a mime-type content type multipart/x-mixed-replace;boundary=boundary-name, the images are separated by boundary-name.

It’s really still a Pull instead of Push because images are sent as one resource in response to GET. The URL looks like this: http://QeyeCamera.com/now.jpg?snap=spush

2. The other server push is truly a Push. For example, browser request 1.htm, but server returns 2.htm, which browser didn’t request, in addition to 1.htm. This is part of HTTP/2 standard.
Nginx started supporting at version 1.13.9
