Here's a paper by Alberto Riva and Marco Ramoni desribing the design and and implementation of LispWeb.
lispweb is a mailing list intended for the discussion of all things dealing with the use of lisp variants for Web development. Many people are finding lisps of various flavors (and that includes Scheme) are wonderful languages for web development. However, there are not many community resources for lisp web development. Often the tools that exist to make this task easier are difficult to find, or effort is being duplicated. Lisp doesn't have the masses of developers that other languages do, so coordinating the limited labor available is very important.
