Rate limiting proxy looking for a specific to-be-decided identifying trait in requests (the "key").
As an example, the script is setup to use the client IP address as the identifying trait.
Based on: https://github.com/nodejitsu/node-http-proxy
The only requirement for this project is NodeJS version 8+.
Clone this repository then install the dependencies:
npm install
Make sure debug is set to false before using it in a production environment.
See config.js for the configuration parameters.
Make sure the logFile path is writable by the user running the script.
Start limiter-proxy.js either using forever start or just node.
In development you can just use npm start.
Configuration will be loaded from config.js, but it's possible to override the port using the first command line argument, as in:
node limiter-proxy.js 8080
While the service is running, always check the log for errors, it's possible that the key map checking function errors and that gets ignored unless the proxy is in debug mode (all keys are allowed all the time).
This can happen if a configuration option is incorrect, for instance.
