Strange characters in http response?

Question

Node.js

The meaning is this. I make a request to the site in this way.

var net = require('net');
 
var srv = net.createConnection(80, 'kartinki24.ru');
 
var buffers = [];
 
srv.on('data', function (data) {
    buffers.push(data);
});
 
srv.on('end', function () {
    var buf = Buffer.concat(buffers);
    console.log(buf.toString());
});
 
srv.write('GET / HTTP/1.1\r\nHost: www.kartinki24.ru\r\nConnection: close\r\n\r\n');

The meaning is that if you scroll to the headers, then after them the !DOCTYPE does not immediately go, but there are some 1cfd characters. (in the attachment). The problem is that these keys are scattered throughout the http request and sometimes it is impossible to correctly assemble it as a whole. Who is familiar with this?

Answer 1

read about Transfer-Encoding: chunked, you see it in the response headers

Answer 2

And it's on almost all sites.
