I don't really need this, but Felix has said he liked the old
way, so maybe he likes this.

On the other hand, I just made
http://bugs.call-cc.org/browser/demonstrations/spiffy/webserver.scm
at his request. Perhaps this is convincingly simple enough to
not need the old style requests.

It sucks, but that's the way it is.

hm, this is interesting.  As you've probably noticed, I've completely
ignored the whole bit about proxies in the RFC.  I think it's time I
start reading this.  Perhaps Apache sends some header that includes the
"real" URI which I could use in Spiffy to update the current-request-uri.

Indeed. However, fastcgi is ready.  You'd need to drop Spiffy then, though.

okay :)

Fair enough :)

I also added an ASCII art diagram indicating the relation
between the different types of URIs.  Perhaps the predicates
make some sense this way.

Cheers,
