Does the default cache_key work with my Nginx setup?

I’m unable to figure out if the default Cache Key Regex is the proper regex to use with my Nginx fastcgi_cache settings. In the plugins default settings the Cache Key Regex is:

/^KEY:\s+https?(?:GET)?([^\/]+)(\/[^\s]*)/m

In MY nginx.conf. my fastcgi_cache_key line looks like this:

fastcgi_cache_key "$scheme$request_method$host$request_uri";

Is it possible to preload with the default Regex key being used in this plugin, or do I need a different REGEX? If I need a different REGEX, then what should I be using?

Thanks for any and all help
