/**
* This file is designed to be the new 'server' of sites using StaticPublisher.
* to use this, you need to modify your .htaccess to point all requests to
* static-main.php, rather than main.php. This file also allows for using
* static publisher with the subsites module.
*
* If you are using StaticPublisher+Subsites, set the following in _config.php:
* FilesystemPublisher::$domain_based_caching = true;
* If you are not using subsites, the host-map.php file will not exist (it is
* automatically generated by the Subsites module) and the cache will default
* to no subdirectory.
