hi,

is there a way to specify a subdomain in expires\_action? i have  
[admin.foo.com](http://admin.foo.com) to edit pages, which are cached in [www.foo.com](http://www.foo.com)  
My update action tries to expire the cache but it seems to look for a  
cache in tmp/views/admin.foo.com/ and doesnt expire the one in tmp/  
views/www.foo.com/
