Transfer a Response object to another process

I am trying to pass an Express’ Response object from child process A to child process B.

In a.js, I am doing the following process.send(process.pid, res.socket);

In b.js, I can get the response socket by using the following

process.on('message', (msg, handle) => {     var output = { msg: msg, socket: handle };     console.log(output);     handle.write('hello there client!'); } 

When I print the contents of output, I do get the msg: 4355 and socket is connected and contains the IP address and port of the connected client. But when I use the socket to write hello there client!, the client did not receive the response. Please help?

My client is Postman.
