http.ClientRequest documentation inconsistencies

[mrgleba]

The documentation for http.ClientRequest states that you can use
setHeader / getHeader / removeHeader but the motheds are not listed below
as methods of this class.

Method addTrailers is also not mentioned although it's there ans it's working.

Would you be interested in submitting a pull request for fixing it @mrgleba ?

(If you have any questions about the technical parts of the process we can gladly help you with that)

[mrgleba]

Will do :)

I honestly have no clue what that means

[mrgleba]

It means that I will prepare the pull request soon.
