The NFS service provides extensions to the mount and automountd commands in Oracle Solaris. These extensions enable the mount request to use the public file handle instead of the MOUNT protocol. The WebNFS service uses the MOUNT protocol as the access method. By using the public file handle, the mount can occur through a firewall. As there are fewer transactions between the server and the client, the mount occurs faster.
The extensions also enable NFS URLs to be used instead of the standard path name. Also, you can use the –public option with the mount command and the automounter maps to force the use of the public file handle. For more information about the WebNFS service, see WebNFS Support.
