How to set http header when calling Open(url String) interface

how to set the http header when load the url?
For example, how to set the cookie header?

I also have the same question.

In my case, I need to make a get request using HTTP/2, or else the server will send a 403 response code. I am eager to try webloop, since I am having trouble using PhantomJS, but is webloop still being maintained?

I am not actively maintaining it myself but I do review and merge PRs.
