[Plugin: W3 Total Cache] W3TC nginx rewrite rules

Hi,

I am hosting 10 sites using symlinked files under 10 different domains. The symlink trick is to make APC store only one version of the file instead of one for each domain (e.g. /var/www/abc.com/wp-login.php and /var/www/xyz.net/wp-login.php).

I’ve configured W3TC to use page-caching with the “disk-enhanced” mode and nginx (not Apache), and in generally it works except for the home page. The problem is that the path to the cache files does not include the HTTP_HOST, so the files are like wp-content/w3tc/pgcache/category/abc/_index.html, while I think they should be wp-content/w3tc/pgcache/xyz.net/category/abc/_index.html

Am I missing something ? I looked for such a setting both in the UI and in the w3-total-cache-config.php but did not find anything.

BTW I am using WP 3.1 and W3TC 0.9.3.1
