Using Apache::Session::Memcached with MasonX::Request::WithApacheSession - perl

Question

I'm trying to use Apache::Session::Memcached in an HTML::Mason project where I'm using MasonX::Request::WithApacheSession to handle my sessions. Unfortunately Apache will not launch when I plug in the Memcached module instead of the MySQL one. My custom handler looks something like this (a few snips here and there):
my $ah = HTML::Mason::ApacheHandler->new (
comp_root => $ENV{HTDOCS},
data_dir => $data_dir,
request_class => 'MasonX::Request::WithApacheSession',
session_use_cookie => 0,
args_method => "mod_perl",
session_args_param => 'session_id',
session_class => 'Apache::Session::Memcached',
session_Servers => '127.0.0.1:20000',
session_Readonly => 0,
session_Debug => 1,
session_cookie_domain => $CONF->{global}->{site_name},
session_cookie_expires => "session",
session_allow_invalid_id => 0,
);
The problem I'm running into is that the session_* paramaters specific to Memcached are not being passed through to Apache::Session::Memcached like the docs say it should. This results in this error:
The following parameter was passed in the call to HTML::Mason::ApacheHandler->new()
but was not listed in the validation options: session_Servers
Now, I have gone through and swapped all of the 3 upper case arguments to lower case, to no avail. And the docs for Apache::Session::Memcached list them as upper case.
Thanks a ton for any help.

It looks like you need to register Apache::Session::Memcached with Apache::Session::Wrapper, following the instructions at http://search.cpan.org/perldoc/Apache::Session::Wrapper#REGISTERING_CLASSES like so (code courtesy Jack M.):
Apache::Session::Wrapper::->RegisterClass(
'name' => 'Apache::Session::Memcached',
'required' => [ [ 'Servers' ], ],
'optional' => [ 'NoRehash', 'Readonly', 'Debug', 'CompressThreshold', ],
);
