Overview
Tasks
An Aqueduct application starts an HTTP server and invokes your code for each request. The code that is invoked might depend on the request's path, method, and other attributes. For example, the request GET /heroes will invoke different code than POST /authors. You configure which code is invoked in an ApplicationChannel subclass; every application declares exactly one ApplicationChannel subclass.
This subclass also sets up services, reads configuration data from files and environment variables and performs any other initialization for your application. For example, an application channel often reads database connection information from environment variables and then sets up a connection to that database.
Aqueduct applications create multiple threads, and each thread takes turn handling incoming requests. Your application channel subclass is created for each thread, creating replica instances of your application.
