Intermediate goal: balance stuff
End(?) goal: round robin load balancing

Handle browsers using the same connection to send multiple requests and also prevent proxy from stalling once the response is completed with keepalive

Add authentication so that user's must provide a valid login and password.

Initially planning to have entire proxy behind login but goal is to selectively require login for backend routes.

Log down visiting IP addresses and incoming requests as well as errors into info_log and error_log

Currently the array of backend hosts is specified each time in getBackend() under main.ts. Instead could read in hosts from the config file.

scanning requests for known bad input (e.g. sqli injections), user agent filtering
