// request.setTimeout() 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);
 
    // Setting the timeout for the client request
    // by using setTimeout method
    req.setTimeout(3000, () => {
        console.log("timeout")
        process.exit(0)
