Answer 1

for those who consider LISP a functional programming language, there's a http server written in common lisp out there, introduced in a 1994 paper and still being developed in 2006:

• http://www.ai.mit.edu/projects/iiip/doc/cl-http/server.html
• http://www.cl-http.org:8001/cl-http/

for more modern stuff, you might want to ask google "haskell web server", you will probably find a few interesting examples. one lead me find this site: http://code.haskell.org/.
