Beta Branch Nginx HTTP/2 & OpenSSL 1.1.0 patch updates

no it's a nginx patch released by Cloudflare for nginx users like ourselves

---

 

yup that's all you need to do with 123.09beta01

 

all unknown answers hence probably why not added to Nginx yet. But Valentin from Nginx is looking into possibility of adding it Re: [PATCH] HTTP/2: add support for HPACK encoding

 

should be ok.. but as i said unknown hence disabled by default

 

no need as NGINX_PATCH='y' is default already in centmin.sh

 

looks ok.. as to issues with IE and Safari test and see

Beta Branch - update nginx HTTP/2 HPACK Full Encoding patch for MS Edge & Safari issues

 

you can enable it for OpenSSL 1.1.0h which is current version if you want though benefits are minimal unless you have alot of traffic (millions of visitors/day).

 

?? Enabling brotli doesn't change Nginx's OpenSSL usage in 123.09beta01

 

Checking that Cloudflare HPACK patch still works on Nginx 1.15.2 + OpenSSL 1.1.0i to improve header compression savings on repeated requests

looking good for HPACK full encoding patch with persistent config set with /etc/centminmod/custom_config.inc

Code (Text):

NGINX_HPACK='y'

to enable Cloudflare's HPACK full encoding patch for Nginx 1.15.2+ - check for --with-http_v2_hpack_enc in nginx -V output
