The http.ClientRequest.reusedSocket is an inbuilt application programming interface of class ClientRequest within the HTTP module which is used to check if the request is sent through a reused socket.
Syntax:
const request.reusedSocket
Parameters: This property does not accept any argument as a parameter.
Return Value: This property returns the object of the client request-host.
Example 1: Filename-index.js
// Node.js program to demonstrate the
// request.reusedSocket method
// Importing http module
const http = require('http');
// Create an HTTP server
const server = http.createServer((req, res) => {
res.writeHead(200, { 'Content-Type': 'text/plain' });
res.end('okay');
});
// Now that server is running
server.listen(3000, '127.0.0.1', () => {
// Make a request
const options = {
port: 3000,
host: '127.0.0.1',
headers: {
'Connection': 'Upgrade',
'Upgrade': 'websocket'
}
};
// Getting client request
const req = http.request(options);
req.host = '127.0.0.1'
// Checking if the message has been
// sent through reusedSocket or not
// by using reusedSocket method
const v = req.reusedSocket;
// Display the result
if (v)
console.log("message is sent through reusedSocket")
else
console.log("message is not sent through reusedSocket")
process.exit(0)
});
Run the index.js file using the following command:
node index.js
Output:
message is not sent through reusedSocket
