Nginx – How to combine squid reverse proxy with nginx proxy for shiny-server

nginxreverse-proxysquid

I have a nginx web server which acts as a proxy for my shiny-server. I now want to use a squid reverse proxy to provide access to the nginx server (and thus the shiny server) to internet clients. Currently, I can access the nginx server (and thus the shiny-server) through a web browser on my local network.

My objective is to configure the Squid & Nginx instances such that they can pass traffic between them.

nginx.conf (edited for brevity):

server {
    listen       80 default_server;
    return       301 https://$host$request_uri;
}

server {

    listen       443 ssl http2 default_server;
    listen       [::]:443 ssl http2 default_server;
    server_name  _;
    root         /path/to/server/directory;

    # Load configuration files for the default server block.
    include /etc/nginx/default.d/*.conf;

    location / {
        proxy_pass http://localhost:3838;
        proxy_redirect / $scheme://$http_host/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
        proxy_read_timeout 20d;
        proxy_buffering off;
    }
}

squid.conf (edited for brevity):

cache_peer shiny.domain.com parent 80 0 no-query originserver name=shinyHost login=PASS
acl shinyACL dstdomain shiny.domain.com
cache_peer_access shinyHost allow shinyACL
http_access allow shinyACL

You don't need squid in reverse proxying mode with nginx, thus you shouldn't use it. If you want to cache anything that upstream gives your nginx - you should do it using nginx ngx_http_proxy_module by configuring what to cache.
