Delete Cache Nginx (Not a virtual box)

Hey folks. I’m running a Laravel Site (Ubuntu) on Nginx (Not a virtual box). When I make changes to a css file, or any file for that matter i’m unable to see the changes right away. I’ve tried changing sendfile from on to off as noted in this link:

And I couldn’t find a Nginx cache file to delete the cache. Many sites recommend going to the “path/to/cache” folder but I can’t find it:

Anyway I don’t believe I set up any kind of proxy caching or anything. Any ideas where I can find my cache so I can delete it folks? For that matter am I looking to do the correct thing here? Thanks for you answer in advance.
