Nginx redirect based on referring URL regular expressions

New to nginx and still trying to figure out its methods.

I'm trying to do a redirect to an external URL based on the referring URL. For example, in the code below that I have for the hosted domain, if the referring URL comes from Facebook, I want to redirect the user to a specific URL:

location / {
index index.php;
    if ($http_referer ~* ^(.*?(\bfacebook\b)[^$]*)$ ) {
           rewrite http://www.othersite.com break;
    } 
try_files $uri $uri/ @handler;
expires 30d; 
}

Nginx doesn't throw any errors once it's restarted, but despite testing this from a Facebook link, it's not executing.

Any nginx / regular expression gurus who can point me in the right direction?

Thanks in advance.

Although it may pass the syntax test, your rewrite statement is incorrect. To redirect any URI to a new URL you would use:

rewrite ^ http://www.example.com/? permanent;

But the preferred solution would be the more efficient:

return 301 http://www.example.com/;

See this page for details of both directives.
