Let's say I have a cluster environment where I basically have the main process (the master) and then I have another 8 worker processes (my cluster). Should the static files be hosted by the main process or should they be hosted on the cluster processes?
If you're using the Node.js built-in Cluster module, the main process should not start an HTTP server, as it will not be able to listen on the same port as the workers. Static files, as with everything else, should be hosted by the workers.
