Dynamic Routing with Circuit
summary
Circuit is a Ruby gem that lets a single Rack server route many domains to different Rack apps and middleware, configured at runtime from a datastore. It uses a cru file and a Site/Node model (Mongoid example shown) to map hosts and aliases to behavior classes, includes a request rewriter to forward paths into downstream Rails routes, and runs in production at about 30-40k requests/day. Current back ends are in-memory and MongoDB, Redis and ActiveRecord adapters are requested.
