This is an "if" inside a "location" which does something other than
"return" or "rewrite...last".

Generally, that's a thing to avoid.

Can you move those three lines outside of the "location" block?

Actually: I suspect that the included file also does "if", so you may
want to move that outside of the "location" block too.

so it may be ok to have them both at server{} level (and applying to
all requests).
