mod_vhost_hash_alias 1.0

mod_vhost_hash_alias is an Apache HTTPD module that allows mass hosting with good distribution across a unified directory namespace.

Administrators no longer have to use complex regexps with mod_rewrite, since they can use mod_vhost_hash_alias to do a better job and use fewer resources.

mod_vhost_hash_alias is a component of the VHFFS hosting platform which is used by the Web hosting provider Tuxfamily.org.
