What i need (TL;DR):

I need to the request headers to be exactly the same as i specify in the http2 request options, it should persist the name casing and the order of all headers.

How can i explicitly set this order or modify them before the request is sent? If is not possible with the default 'http2' library, please let me know any other lib that is capable of doing this.

If you need a little more context, keep reading!

What happens now:

When i perform a HTTP/2.0 request with 'http2' library, all the headers names seems to be normalized to lowerecase and it's order is changed before the request is sent.

Exemple code that i use to perform a HTTP/2.0 request:

const http2 = require('http2');

const client = http2.connect('http://localhost:8000');

const request = client.request({
  ':method': 'GET',
  ':authority': 'localhost:8000',
  ':scheme': 'https',
  ':path': '/',
  'sec-ch-ua-mobile': '?0',
  'sec-ch-ua': `" Not A;Brand";v="99", "Chromium";v="99", "Google Chrome";v="99"`,
  'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.51 Safari/537.36',
  'Cookie': 'foo=bar',
});

request.end()

The headers order i expect to recieve on the server:

:method: GET
:authority': localhost:8000
:scheme': https
:path: /
sec-ch-ua-mobile: ?0
sec-ch-ua: " Not A;Brand";v="99", "Chromium";v="99", "Google Chrome";v="99"
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.51 Safari/537.36
Cookie: foo=bar

What i actually recieve on the server:

:path: /
:scheme: https
:authority: localhost:8000
:method: GET
sec-ch-ua-mobile: ?0
sec-ch-ua: " Not A;Brand";v="99", "Chromium";v="99", "Google Chrome";v="99"
user-agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.51 Safari/537.36
cookie: foo=bar

Note that the casing of all headers and the order of :path, :scheme, :authority and :method headers are different from what i expect them to be...

I already investigated the source code of http2, seems it is not possible to explicitly define the order of this 4 headers and disable this naming lowercase normalization. Many of the existing HTTP/2.0 libraries for node relly on the native lib, thus, carring this problem with them.

But here we goes nothing, how can i explicitly set this header order or modify them before the request is sent to match what i expect? Exists any library or library binding that allow a way to achive this in Node JS?

PS: already tried node-libcurl and it have the same problem.

Thanks!
