Using handler lists means that *order matters*, much as the
class-precedence-list order always matters for method dispatch. And
furthermore, as all Hunchentoot can see is a list of functions, it has
no way of "doing what you mean".
For example, let's pretend that the Hunchentoot dispatcher list looked
like this:
((("foo") . show-foo)
(("bar") . show-bar)
(("foo" "hapless") . show-foo-hapless))
Where you intend for /foo or /foo/1 or /foo/hello to invoke show-foo,
/bar/* to invoke show-bar, and specifically /foo/hapless/* to invoke
show-foo-hapless. Because Hunchentoot can see the details of your
prefixes, it can sort the dispatchers longest-first so that
show-foo-hapless gets to handle /foo/hapless/baz instead of show-foo.
However, if the list looks like this instead:
(show-foo show-bar show-foo-hapless)
then the prefix matcher inside `show-foo' will capture it. Of course,
the reason Hunchentoot uses the latter is that any published matching
scheme would be limited by its publication; you would preclude or
override any different criteria Hunchentoot users might like to use.
Even using an alterable list of functions instead of a straight function
has the side effect of making it so that *order matters*.

In other words, since you're playing with dispatchers yourself, you
should familiarize yourself with Weblocks's own dispatchers. We have
two. Look at src/server.lisp.
(Hint: is your webapp's prefix ""?)
