UNSTABLE: New API, yet to be vetted.

Create a custom HttpClient for to use with fetch. This is an extension of the web platform Fetch API which allows Deno to use custom TLS certificates and connect via a proxy while using fetch().

const caCert = await Deno.readTextFile("./ca.pem");
const client = Deno.createHttpClient({ caCerts: [ caCert ] });
const response = await fetch("https://myserver.com", { client });

const client = Deno.createHttpClient({
  proxy: { url: "http://myproxy.com:8080" }
});
const response = await fetch("https://myserver.com", { client });
