Hi, This package is used to convert a vhost into a hash. For example, you have many virtualhost on your apache, you can use mod_hash. When your apache will receive a request for the servername aaa.com, mod_hash will take the md5sum and get the files from it. For example, with the servername "foo.com", apache will search files in 16/7a/04/18 directory. -- Julien
