curl doesn't do anything secret magic and isn't using any "tricks". It just
does HTTPS by the book.

I'm not aware of what "bypass" you say curl manages to do, but if there's any
difference between curl and other clients it is either due to the server
detecting a difference or that the other clients did some mistake.
