At the following piece of documentation (for v12; the latest one):

• https://nodejs.org/dist/latest-v12.x/docs/api/http.html#http_message_url
• https://github.com/nodejs/node/blob/master/doc/api/http.md#messageurl

It describes:

To parse the url into its parts require('url').parse(request.url) can be used:
[…]
…or true can be passed as the second argument to require('url').parse:
[…]

However, this legacy url module/API is deprecated since v11.

Thus, the documentation should be updated.

Bonus points for grepping the rest of the documentation to find other outdated examples.
