node.js - Serve mp3 through TCP server -

i'm trying serve mp3 file through tcp server adding headers emulate http server. headers i'm using are:

var header = `http/1.1 206 partial content\r\ncontent-type: audio/mpeg\r\ncontent-length: ${filestat.size}\r\n'cache-control: no-cache'\r\nconnection: keep-alive\r\nlast-modified: ${date.togmtstring()}\r\n\r\n` 

an way create server:

let server =  net.createserver((socket) => {     socket.on('data', (data) => {       socket.write(buffer(header, 'ascii'))       rnfetchblob.fs.readstream('/storage/sdcard1/music/elpisito.mp3', 'ascii')       .then((stream) => {         stream.open()         stream.ondata((chunk) => {           socket.write(buffer(chunk, 'ascii'))         })         stream.onend(() => {           socket.end()         })       })     }   })   socket.on('error', (error) => {     console.log('error ' + error)   }) }).listen(serverport, '0.0.0.0', () => {   console.log('opened server on ' + json.stringify(server.address())) }) 

if don't send header (i delete socket.write(buffer(header, 'ascii'))) download file sample request looks this:

http://192.168.0.12:65000/song.mp3 

the problem want serve song streaming don't know how handle requests , how set proper header.

this snapshot of sample request:

as can see in server code, response written socket.write , triggered in data event handler have access data info requests. snapshot of first (there two) request data:
