I have a website with subdomains set up, the naked domain without any subdomain gets cached by boost and there is the message by boost in the footer. But any subdomain does not get cached. We are using the sites module http://drupal.org/project/sites, to split the subdomains into different drupal sites.
We have this error on the status report page - Boost crawler did not get a 200 response; 302 returned instead.
my boost settings
