http request with header "constructor" results to a value of "function Object() { [native code] }, "

[ravenjohn]

I'm using Node v5.3.0 on Windows 10. I was playing with http and found out that a request with a header name constructor results to function Object() { [native code] },

Simple HTTP Server

const http = require('http');

http.createServer((request, response) => {
 response.end(JSON.stringify(request.headers, null, '\t'));
 })
 .listen(8000);

Request

const net = require('net');
const client = new net.Socket();

client.connect(8000, '127.0.0.1', () => {
 client.write('GET / HTTP/1.1\r\nconstructor:\r\n\r\n');
});

client.on('data', (data) => {
 console.log(data.toString());
 client.destroy();
});

client.on('close', function() {
 console.log('Connection closed');
});

Output

HTTP/1.1 200 OK
Date: Mon, 28 Dec 2015 21:17:55 GMT
Connection: keep-alive
Content-Length: 59

{
 "constructor": "function Object() { [native code] }, "
}
Connection closed

I've got a patch to fix this coming soon...
