Change limit not working in Heroku app?

[IshwarBhat]

I was not sure where to ask for help with this, hence raising an issue here. Any help is appreciated.
I tried running freegeoip as a Heroku app by first cloning the app source code in my local Windows machine. I need to increase the limit of 10,000 requests per hour. To do this, I tried two methods:

1. Change the contents of apiserver/config.go by adding a line RateLimitLimit: 0, inside func NewConfig() *Config { return &Config{ } }
2. Create a file prod.env with the line FREEGEOIP_RATELIMITLIMIT=50000
   Neither of which worked. When I open my app home page, I still see

9997 calls remaining, resets in 59 minutes

Where am I going wrong?
