Preserve header names

[Cooya]

I am sending requests to a server which does not respect HTTP specification specifying that headers should be case-insensitive. The problem is that with got-scraping, a header named "MyHeader" will be renamed "Myheader"...

How can I send a header whose name will be kept untouched ?

I tried using a hook without success :

let { gotScraping } = require('got-scraping');

gotScraping = gotScraping.extend({
  hooks: {
    beforeRequest: [
      options => {
        options.headers['myheader'] = options.headers['MyHeader'];
        delete options.headers['myheader'];
      }
    ]
  }
});
