Hello,
Is it possible to add a custom header to avoid throttling by such tools as Akamai etc.?
For example, check of https://darphin.com/ will always timeout.
I'm using yellowlab tools as an example but it fails in CLI too.

But with adding a custom request header this problem is gone. Such a feature is available on https://webpagetest.org

Please let me know if it's possible. I can also contribute but would appreciate a direction to make it happen faster. Thank you.
