No, but that's the way many of them work. mod_lisp takes another
approach--it talks directly from Apache to a running Lisp instance--but
frankly I never had much luck getting it working under my setup. And
it's kinda nice having a little web server--makes testing and
development a bit easier.
A similar setup is used for Pylons, a Python web development framework:
the paste web server is run behind the scenes and Apache (or whatever)
sits in front of it.
You could if you wanted _just_ run the Lisp webserver, but I like having
Apache in front, as it offers a lot of nice features.

CLSQL is a package available online; Google will lead you to it, or

Ah, you meant web sessions. I'm not familiar with the mechanism, so I
Googled a bit and the only references were to TCP/IP session hijacking.

I daresay that you're probably correct, although I will note that, at
least for those Lisp frameworks I've used which provide sessions, one
doesn't need to write one's own session code--and hence one can rely on
the time and effort of someone else. So you & I needn't be great
programmers--just the guy who writes the framework.

Well, different packages support different implementations. So if you
use several packages then you can only use an implementation supported
by _all_ of them (in mathematical terms you're limited to the
intersection of the sets of supported implementations). Today in the
free Lisp world it appears that the most commonly supported
implementations are SBCL and clisp.

CLiki? Are you on a slow link? It's typically very fast for me.
Perhaps it's undergoing maintenance or is under attack from some script
