'add_header' no longer allowed inside 'if', even though document says it is?

Hi again,

And ugh, yet again realising what I did wrong right after hitting "send":

Because I didn't put the if inside a location.

Answering my own question: "add_header" can only be inside an "if" 
that's inside a "location".
I have no "location" for the root, so I figured it could be inside "server".
