Apache attempting to load from /var/cache for munin - apache

Question

I'm trying to get the Munin webpage working under Apache2 via SSL on Debian Etch. My config for the website is:
NameVirtualHost 1.2.3.4:80
<VirtualHost www.mydomain.org:80>
ServerName www.mydomain.org
...
<Directory /var/www/https>
AllowOverride None
Order deny,allow
Deny from all
</Directory>
...
</VirtualHost>
<VirtualHost www.mydomain.org:443>
ServerAdmin webmaster#localhost
DocumentRoot /var/www/https/
SSLEngine On
SSLCertificateFile /etc/blah
SSLCertificateKeyFile /etc/blah
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
...
<LOCATION /munin>
Options Indexes FollowSymLinks MultiViews
AuthType Basic
AuthName "Munin Users"
AuthUserFile /etc/apache2/auth-files/munin
<limit GET PUT POST>
require valid-user
</limit>
Order allow,deny
allow from all
</LOCATION>
...
</VirtualHost>
Munin is configured to use the directory and the files are created and refereshed in the proper location. I can go to https://www.mydomain.org/munin/, enter a username and password, and see the top page fine. But when I try to drill down to the actual information, I get a 404 error:
Not Found
The requested URL /munin/localdomain/localhost.localdomain/apache_accesses.html was not found on this server.
The URL listed is the same URL that's in the URL of the browser window. But when I look in the error log, I see:
File does not exist: /var/cache/munin/www/localdomain/localhost.localdomain/apache_accesses.html, referer: https://www.mydomain.org/munin/localdomain/index.html
The index.html file lists the file name as localdomain/localhost.localdomain/apache_accesses.html.
I do not have the cache module loaded:
root#etch:/etc/apache2/mods-enabled# ls
alias.conf authz_default.load autoindex.load dir.conf mime.load reqtimeout.conf ssl.load alias.load authz_groupfile.load cgi.load dir.load negotiation.conf reqtimeout.load status.conf auth_basic.load authz_host.load dav.load env.load negotiation.load rewrite.load status.load auth_digest.load authz_user.load dav_fs.conf include.load php5.conf setenvif.conf authn_file.load autoindex.conf dav_fs.load mime.conf php5.load setenvif.load
I do not have any directives to enable caching in my apache config:
root#etch:/etc/apache2# grep -i cache *
apache2.conf:#SSLSessionCache dbm:/var/cache/apache2/ssl_cache
apache2.conf:SSLSessionCache none
(The dbm cache line is commented out and I've restarted apache numerous times.)
root#etch:/etc/apache2/sites-enabled# grep -i cache *
(zero lines returned.)
So why in the heck is apache trying to load the files from the /var/cache directory rather than the /var/www/https/munin directory? Any help greatly appreciated.

I do not know for certain how it works on Debian, but the Ubuntu package for munin creates a config file in /etc/apache2/conf.d/munin.
This config file specifies an alias for /munin : Alias /munin /var/cache/munin/www
/var/cache/munin/www is the default htmldir value for recent munin versions.
