More than one can say for the CLIM examples :-)

Try http://wilson.ai.mit.edu/cl-http/show-documentation?HTTP:EXPORT-URL
Of course, if you rather read the source code, ....this is one that wizards
just love -- especially if their development environment sucks on macros.

Simon, you probably ought to try some copy and edit from the example code
found in http:examples; (http://wilson.ai.mit.edu/cl-http/sources/examples/)
Start with exports.lisp, then look at documentation.lisp
This will get you started with your own computed pages.
Check out w3p which has documentation and examples when you want
to move up to presentations. You dont want to duplicate code forever
in your input validators.
If you're feeling that you want to wow people, check out the VRML
generation facility.
The mail hyperarchive is a more advanced example suitable for
people who want to export their whole system via one form.

One of the things that apparently caused buffer overflow for Franz
was that CL-HTTP attempts to capture and present a set of abstractions
(theory) describing the entire http process. Although this provides
the experienced Lisp hacker with complete control, at the same time,
it confronts him with a small sea of abstractions. Many of us
are used to writing systems like this. Those that are not may not
have the navigational skills for working through so many abstractions.
Exported symbols are a good hint that something is worth knowing about.
Internal symbols can be safely disregared. Even then, it would be desirable
to identify the smallest working set necessary to do useful things, which should
be documented in a way that we can extend it as the server, client, web
walker and coming modules evolve.
For present purposes, I would recommend learning one capability at a time
and exploring around the area a little. The exports.lisp file should do this
for you.

Nice web pages. You might be generating some dangerous stuff when you get
done wrapping your head around cl-http.
