Haskell server pages through dynamic loading

Abstract

Haskell Server Pages (HSP) is a domain specific language, based on Haskell, for writing dynamic web pages. Its main features are concrete XML expressions as first class values, pattern-matching on XML, and a runtime system for evaluating dynamic web pages.The first design of HSP was made by Erik Meijer and Danny van Velzen in 2000, but it was never fully designed nor implemented. In this paper we refine, extend and improve their design of the language and describe how to implement HSP using dynamic loading of pages.
