Is there a better way to disable HTTP keep-alive? (connection: close)

[nwtgck]

Hi, undici.request() requests with connection: keep-alive by default. Specifying headers: { 'connection': 'close' } causes "InvalidArgumentError: invalid connection header" error.

I found dispatcher: new undici.Agent({pipelining: 0})disables keep-alive as follows.

const undici = require("undici");

(async () => {
  const res = await undici.request("http://localhost:8181", {
    dispatcher: new undici.Agent({pipelining: 0}),
    body: "hello",
  });
})();

$ nc -lp 8181
PUT / HTTP/1.1
host: localhost:8181
connection: close
content-length: 5

hello

Is there any better way to disable HTTP keep-alive? I mean "better" is that it is clear to understand for everyone, new Agent({pipelining: 0}) is not clear for me.
