+This is a reduced disk-IO version that does not write the HTML or JSON files to disk.
+It writes them to a redis-backed memory store which then can be quickly retrieved by a webserver
+without hitting the disk at all. See nginx's HttpRedis2Module module for more of what I mean.
+
+If you don't have HttpRedis2Module, i've included a 404.php that you can use with an htaccess like:
+
+# for /vichan/* base
+RewriteEngine On
+RewriteRule ^[^/]+/$ %{REQUEST_URI}/../../404.php [NC,L]
