Release 2.0 now reuses the Apache → Lisp sockets, boosting performance by a factor from 40 to 80.

I have ported mod_lisp for the Lighttpd server. It implements exactly the same web-server Lisp protocol as the original mod_lisp, so, Apache can be replaced with Lighttpd seamlessly, without any change noticeable from the Lisp side's point of view (well, actually, you'd get different server-baseversion and modlisp-version headers). The code base is largely independent of the v. 2.43 where it took off, though, and it has its own version numbering scheme. See the project page for installation and configuration instructions.
From the repository: "mod_lisp-lighttpd has been phased out and is no longer actively maintained."
Chris Beggy has written the nice tutorial below: mod_lisp 2.2 + apache (of course) + cmucl + clsql + lml + uffi + mysql were used to create a simple dynamic database website which explained installation, did some advocacy, shared some code, and incorporated the comments of visitors.
