Ashd is an HTTP server that follows standard Unix philosophy for modularity. Instead of being a monolithic program with loadable modules, as most other HTTP servers seem to be, Ashd is simply a collection of much simpler programs, passing HTTP requests to each other using a simple protocol. The model also allows such handler programs to persist properly, so that, for example, session data can be kept in memory, connections to back-end services can be kept open, and so on.
