Reverse Proxy

https://www.nginx.com/resources/admin-guide/reverse-proxy/

https://www.youtube.com/watch?v=Dgf9uBDX0-g  – by Zariga Tongy

 

Local Device client User -> Public Internet -> Reverse Proxy -> Origin Web Server IP

 Client를 대신해서 목적서버의 network resource를 request하는 proxy server

  • client side의 설정이 전혀 필요없다.
  • Network request를 투명하게 처리할수 있다. 
  • Security를 위한 하나의 Layer를 얻을 수 있다. 
  • load balancing이 가능하다.

 

cf. Forward Proxy :  Local Device client User -> Proxy -> Public Internet

https://www.techandme.se/set-up-nginx-reverse-proxy/

 

(Optional) Serving to a custom domain with clean URLs (no :3838 links)

Now we have shiny installed and configured properly.
You’ll still need to set it up to serve the files to your actual website address however. I updated my nginx configuration (/etc/nginx/sites-enabled/default or /etc/nginx/sites-enabled/) to add a block for shiny. This allows you to host on yoursite/shiny. This is a reverse proxy and allows you to get around porting issues

location /shiny/ {
    proxy_pass http://127.0.0.1:3838/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
}
