Joe,
I don't think that that approach will work in the long term. What if
someone wants to serve a file *.xyz in the future? You would have to
adjust  that regex. And again, and again...

I think it would be much easier to set up <DirectoryMatch 'regex'> and
<FilesMatch 'regex'> sections for what you want to serve by your
handler(s), and let Apache handle _all_ other files/dirs.

Filter on what is the smaller set - and I think that's your dirs and .html
files. All other files not mentioned in those <*Match ...> sections are
automatically handled by Apache. Further - a regex matching all those files
you don't want to handle yourself would be rather lengthy and unwieldy.

Take a look at Apaches fine documentation, look for <DirectoryMatch ...>
and <FilesMatch ...> directives.
http://httpd.apache.org/docs/2.2/mod/core.html#directorymatch
http://httpd.apache.org/docs/2.2/mod/core.html#filesmatch

For example, a <FilesMatch ...> for . htm or .html Files would look like
(untested):

    PerlRequire /var/www/mysite/cgi-bin/my_modperl_module.pm

    <FilesMatch "\.html?$">
        SetHandler perl-script
        PerlResponseHandler my_modperl_module   # which contains a sub
handler {...};
    </FilesMatch>

Cheers,
Ekki
