you can also just to do:
<Location /parts>
SetHandler modperl
PerlResponseHandler My::Parts::Handler
</Location>
And handle the validation of the rest of the URL within your ResponseHandler.
You could implement as much depth below /parts as you want. api calls you'll
probably want to use are
$r->location (in this case, would return /parts)
$r->uri (the actual URI requested)
i have a number of Handlers that aren't doing REST, but do work on the same
sort of principle. I use this utility function to parse take a request object
and give me an array of all it's bits. it compacts multiple /'s into a single
one because that's what apache would do with them by default. I'm pretty sure
that Apache::Dispatch does something very similar to this.
sub parse_request {
my $r = shift;
my $uri = $r->uri;
#
# compact /'s
#
$uri =~ s|\/+|\/|gi;
#
# strip the location off the front of the uri
#
my $location = $r->location;
$uri =~ s|^$location/?||;
#
# split what's left
#
my @split_uri = split '/', $uri;
#
# return a reference to the array
#
return [EMAIL PROTECTED];
}

This is the sort of things that Catalyst would excel at, especially
if you have several nesting levels (i.e. parts/1234/subpart/567/form).
See Catalyst doc at
http://search.cpan.org/~jrockway/Catalyst-Manual-5.701003/lib/Catalyst/Manual/Intro.pod.
But if you don't need that complexity, you can easily do it in mod_perl :
configure Apache with something like
<LocationMatch "/parts/\d+$">
SetHandler modperl
PerlResponseHandler My::Parts::Handler
</LocationMatch>
and then have your module My::Parts::Handler parse the URL and get to the part
number.
Good luck, L. Dami
