Thanks. This is pretty much the handler which I'd previously written,
with the the exception of s/use/require/. I'll probably either go with
Apache::Dispatch, using the DispatchRequire option, or write something
custom.

I just took a look at Apache::Dispatch and I get he impression that if I
were to use it then I would have to either PerlModule 'all' my subclasses
beforehand, or alternateively use the DispatchRequire option anyway. I'm
already using StatINC so I'm going to have to do a toss between code which
I've already written and converging to the Apache::Dispatch interface.
I'm not so keen on loading all the inheriting classes into memory
beforehand, nor setting up multiple handlers for each location. It's a
fairly large site and my main concern was to do with how I should store
the correspondence from uri to object.

I could just map from URLs to the specific control subclasses and then use
Dispatch to require them - I'd already started on writing a mapping from
path names to relative namespaces. I was still 'eval/use'ing the
Modules though.
How does StatINC behave with 'required' packages?
Hmm.. it's "make your mind up time. ;)
Thanks for the tips.
Cheers,
