This is the WebDAV demo. It is attempting to expose /tmp from the native filesystem to the URL /dav. Try it out with a WebDAV client such as Cadaver. Or depending on your operating system you can just mount this URL as a local filesystem.
For example on OS X try a command lile:
$ mkdir /Volumes/dav-mount $ mount_webdav http://localhost:8080/dav /Volumes/dav-mountOn Windows systems you can mount this share using a command like:
C:\> net use * "http://localhost:8080/dav"
