Excluding URLs from SuperCache

Hi. Trying to avoid caching certain pages (e.g. /add-a-quote/), I've added that string in the exclusions list under WP-SuperCache Advanced. I've also added this to the nginx server config:

if ($request_uri ~* "(/add-a-quote|/random-story|/contact-form|/wp-admin/|/xmlrpc.php|/wp-(app|cron|login|register|mail).php|wp-.*.php|/feed/|index.php|wp-comments-popup.php|wp-links-opml.php|wp-locations.php|sitemap(_index)?.xml|[a-z0-9_-]+-sitemap([0-9]+)?.xml)") {
set $cache_uri 'null cache';
}

---

But it still keeps caching that page. Any ideas?

 

Yes I've tried that.

 

OK I figured it's because my URLs are having the / removed at the end.

So loading the site with /add-a-quote causes it to cache. Loading the site with /add-a-quote/ causes it to not cache. Is it supposed to have a slash at the end automatically?

Also does this mean the Supercache settings Wordpress side for rejected URIs dont work? Everything is set in nginx config?
