Beta Branch add NGINX_SPDYPATCHED variable support 123.09beta01

add NGINX_SPDYPATCHED variable support 123.09beta01

Disabled by default with NGINX_SPDYPATCHED='n'. Experimental HTTP/2 + SPDY Cloudflare Nginx patch support as outlined at https://blog.cloudflare.com/open-sourcing-our-nginx-http-2-spdy-code/ and discussed https://community.centminmod.com/threads/http-2-spdy-patch-for-nginx-1-10-nginx-1-11.7516/. Nginx patch made for Nginx 1.9.7 so no guarantees it works on Nginx 1.11.1.

To enable patch set in persistent config file you create or append at /etc/centminmod/custom_config.inc the variable

Code (Text):

NGINX_SPDYPATCHED='y'

Then centmin.sh menu option 4 to recompile Nginx 1.11.1 or higher. Then double check your nginx vhost config files that listen option line contains both spdy and http2 flags.

To disable patch comment out the line or set in /etc/centminmod/custom_config.inc

Code (Text):

NGINX_SPDYPATCHED='n'

Then centmin.sh menu option 4 to recompile Nginx 1.11.1 or higher. Then double check your nginx vhost config files that listen option line contains only http2 flags.

Note there's no guarantee this works on subsequent Nginx 1.11.1+ version updates and may break which maybe problematic if newer Nginx versions involve security updates you want to update for.

yeah did try on nginx clean, could be 3rd party who knows.. will try again later

line 445 is related to the middle line of src/http/modules/ngx_http_ssl_module.c

Code (Text):

#if (NGX_HTTP_V2 || NGX_HTTP_SPDY)
    }
#endif

Patch basically didn't cleanly update the right lines

SSLLabs test reports NPN and SPDY/3.1 support + ALPN and HTTP/2 support

 

This patch no long useful as browsers have deprecated spdy so consider it disabled

also currently sslspdy site server had to be reinstalled so hasn't been setup with HTTPS
