WebNFS provides the capability to make a file system on the Internet accessible through firewalls. This capability uses an extension to the NFS protocol. One advantage of using the WebNFS protocol for Internet access is its reliability. The service is built as an extension of the NFS Version 3 and Version 2 protocol. Additionally, WebNFS enables you to share files without the administrative overhead of an anonymous ftp site.
