url-resolver

Resolves an url using a routing rules in routing.json. Routing complex load-balancing rules or routing an endpoint to both http and https endpoints is a non-trivial task using something like nginx. Sometimes you just want to resolve the actual connection url based on simple weighted load-balancing rules without generating ssl certificates if the upstream has both http and https endpoint.

This is a simple golang api that resolves the url based on routing rules in a json config rule file.
