That's a very good point and I understand that. But webhat's comment makes it seem like the whole article is invalid or the example is not correct. I definitely would not consider this as an 'obvious error' with the example. Maybe bad practice. Would you say the copy/paste issue is solved if the author just does a mass replace from 'http' to 'https' on his articel?
I would say yes, I've also advised the author of this mistake and he declined to modify it. This is the less that friendly reply I got:
> You missed the absence of Content-Length in some of my examples? If you're going to be on this internet, friend, you've got to step up your pedantry game.
