Hi Ray. If the node.js was running on realserver.com:5000. For the
Reverse Proxy I first set up a DNS alias for the server (ie. myapp.com to
realserver.com.) The reverse proxy in NGINX would look something like this:
server {
listen 80;
server_name myapp.com;
location / {
proxy_pass http://localhost:5000/;
}
}
When the user browses to myapp.com (no port #) it gets redirected to
realserver.com>localhost:5000.
This is 1 way to eliminate the user to enter a port #.
All the best,
Grant.
