Overview

This HOWTO describes a web server written for the day when even Yaws is not quick enough.

The web server presented is quite simple. Even so it is split into 5 modules. Some of these are dictated by the OTP framework, and others are split out for convenience. The 5 modules are:

  • iserve - API for managing URIs and callbacks
  • iserve_app - OTP Application behaviour
  • iserve_sup - OTP Supervisor
  • iserve_listen - Gen_server to own the listening socket and create connections
  • iserve_socket - Process to handle a single HTTP connection for its lifetime


This HOWTO presents code and descriptions for each of these as they arise.
