nginx reject request if header not present

I need nginx to reject requests if header StaticCookie is not present. I don't care about its value, I just need for it to exist.

What I came up with is this, but this doesn't work. Nginx allows requests with no headers at all.

 if ($http_StaticCookie = false) { return 403; } root /usr/share/asuno/www; location ~* /css/ { expires max; } location ~* /js/ { expires max; }

I saw this post -Nginx: Reject request if header is not present or wrong - but it deals with defined header values. What I need is to check mere existence of the header.

I tried putting location directives inside the if clause but then nginx throws errors trying to read the config.

How can this be done?

the comment by Alexey Ten is correct, thanks.

if ($http_StaticCookie = "") { return 403; }
