How to use a reverse proxy server to hide the real server's information?

To use a reverse proxy server to hide the real server's information, you can follow these steps:

Step-by-Step Guide:

1. Set Up the Reverse Proxy Server:

   • Install a reverse proxy server software like Nginx or Apache.
   • Configure the reverse proxy to accept incoming requests and forward them to the actual server.

2. Configure the Reverse Proxy:

   • Modify the server's configuration file to include the reverse proxy settings.
   • Specify the IP address and port of the real server that the proxy will forward requests to.

3. Hide Server Information:

   • Remove or modify server headers in the response to avoid exposing details about the real server.
   • For example, in Nginx, you can set server_info off; and server_tokens off; in the configuration file.

4. Test the Configuration:

   • Restart the reverse proxy server to apply the changes.
   • Use tools like curl or browser developer tools to inspect the response headers and ensure that server information is hidden.

Example Configuration in Nginx:

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://real_server_ip:port;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;

        # Hide server information
        server_info off;
        server_tokens off;
    }
}
