An application needs to maintain the remote client address for managing the number of requests from a computer system and tracking its usage. But sometimes, the server runs behind an NGINX server, so we need to check its forward request. For this purpose, we can use "x-forwarded-for"Syntaxreq.headers['x-forwarded-for'] || req.socket.remoteAddressIf the proxy isn't yours, one should be careful while using the x-forwarded-for header, because it can be spoofed.Example 1Create a file with the name "remoteAddress.js" and copy the following code snippet. After creating the file, use the command "node remoteAddress.js" to run this code as shown in the example below −// ... Read More

The app.disabled() method checks and returns True if the property name passed is set to False or is disabled. If not, we can disable the property by using the app.disable() method.Syntaxapp.disabled( name )Example 1Create a file with the name "appDisabled.js" and copy the following code snippet. After creating the file, use the command "node appDisabled.js" to run this code as shown in the example below −// app.disabled() Method Demo Example // Importing the express module const express = require('express'); // Initializing the express and port number var app = express(); // Initializing the router from express var ...
