Case insensitive location

[Callumpy]

Hello there, i'm hoping someone can help me out with this. I've tried many
different things but none have worked for me so far.

Here is my location block:

location ^~ /card/ {
                root /home/site/public;
                rewrite ^/card/([a-zA-Z0-9_+]+)/(.*).png$
/card.php?name=$2&type=$1 last;
                expires epoch;
        }

Some requests for images are being made with a capital 'C' in 'Card' and are
causing 404s.

I've tried changing the location to "~* ^/card/" but that didn't work, is
there anything else I could try?

Thanks in advance.
