Usage in Deno

import { Http2ServerResponse } from "node:http2";
Http2ServerResponse.prototype.appendHeader(
name: string,

): void

Append a single header value to the header object.

const server = http2.createServer((req, res) => {
  res.setHeader('set-cookie', 'a');
  res.appendHeader('set-cookie', 'b');
  res.writeHead(200);
  res.end('ok');
});
