Abstract
A new URL scheme, 'nfs' is defined. It is used to refer to files and
directories on NFS servers using the general URL syntax defined in
RFC 1738, "Uniform Resource Locators (URL)".
This scheme uses the public filehandle and multi-component lookup
[RFC 2054, RFC 2055] to access server data with a minimum of protocol
overhead.
The NFS protocol provides access to shared filesystems across
networks. It is designed to be machine, operating system, network
architecture, and transport protocol independent. The protocol
currently exists in two versions: version 2 [RFC 1094] and version 3
[RFC 1813], both built on ONC RPC [RFC 1831] at its associated eXternal
Data Representation (XDR) [RFC 1832] and Binding Protocol [RFC 1833].
