I'm still having no luck with it.

As I said before, when I use location ~* ^/card/, it just 404s all the time unless I disable my cache.

Here is my cache code, I have no idea why it does this.

# Cache setup.
location ~* \.(jpg|jpeg|png|gif|ico|css|xml|js|woff)$ {
expires 30d;
root /home/site/public;
add_header Pragma public;
add_header Cache-Control "public, must-revalidate, proxy-revalidate";
}
