Lisplets are Java Servlets that forward their requests, and gather their response headers, using s-expressions over sockets. They enable easy integration of Common Lisp or Scheme into a Java-based web environment.
The Lavlet HTTP server and Lisp Server Pages engine is a complete ANSI Common Lisp webserver and dynamic pages engine for Lisp modeled after JSP/Servlet/Tomcat and ASP/IIS.
