nginx cache expire settings issue.Can anyone help?

[anoopov]

Hi I am new to Nginx. I need to add expire -1 for my JSON files in the below
urls

https://siteaddress/foldername /default.htm#/dashboard/ui.json


location /foldername {
	   index  default.html default.htm;
       proxy_pass         http://siteaddress_eapp_entry;
    }


I have tried below syntax but still JSON files are caching

location  \foldername \.(json)$ {
                    expires -1;
           }  

Please help anyone to solve my issue,Thanks in advance.
