@ahmadnassri Thank you for your contribution!

A nit: it seems the message of the first commit violates line length requrements. Could you wrap the lines? And maybe it is better to clean out markdown link code.

So the commit message can be something like this:

doc: fix http properties documented as methods At 9772fb9 `maxHeadersCount` and `timeout` were erroneously changed to methods. `maxHeadersCount` was also listed to default to `1000` where it actually is `2000` Refs: https://github.com/nodejs/node/blob/e0a9ad1af244f8756a228a6d087b3a55ee4c0d14/lib/_http_server.js#L276 Refs: https://github.com/nodejs/node/blob/e0a9ad1af244f8756a228a6d087b3a55ee4c0d14/lib/_http_server.js#L273 Refs: https://github.com/nodejs/node/blob/e0a9ad1af244f8756a228a6d087b3a55ee4c0d14/lib/_http_server.js#L312 

Or even like this (in the message of the landed commit there will be a link to this PR, so all your links will be available):

Should this be backported to v6.x-staging? If yes please follow the guide and raise a backport PR, if no let me know or add the dont-land-on label.
