Michael Hanus: 

Web Server Programming in Curry
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Abstract:

We propose a new approach to implement web servers based on the Common
Gateway Interface (CGI).  Since we use the multi-paradigm declarative
language Curry as an implementation language, many of the drawbacks
and pitfalls of traditional CGI programming can be avoided. For
instance, the syntactical details of HTML and passing values with CGI
are hidden by a wrapper that executes abstract HTML forms by
translating them into concrete HTML code.  This leads to a high-level
approach to web server programming where notions like event handlers,
state variables and control of interactions are available.
