Abstract

   This document describes the specifications for a server of WebNFS
   clients.  WebNFS extends the semantics of versions 2 and 3 of the NFS
   protocols to allow clients to obtain filehandles more easily, without
   recourse to the portmap or MOUNT protocols.  In removing the need for
   these protocols, WebNFS clients see benefits in faster response to
   requests, easy transit of firewalls and better server scalability
   This description is provided to facilitate compatible implementations
   of WebNFS servers.
