Abstract

   This document specifies the gopher Uniform Resource Identifier (URI)
   scheme that was originally specified in RFC 1738.  The purpose of
   this document is to allow RFC 1738 to be made obsolete while keeping
   the information about the scheme on standards track.

1.  Introduction

   URIs were previously defined in RFC 2396 [RFC2396], which was updated
   by RFC 3986 [RFC3986].  Those documents also specify how to define
   schemes for URIs.

   The first definition for many URI schemes appeared in RFC 1738
   [RFC1738].  Because that document has been made obsolete, this
   document copies the gopher URI scheme from it to allow that material
   to remain on standards track.

2.  Scheme Definition

   The gopher URL scheme is used to designate Internet resources
   accessible using the Gopher protocol.

   The base Gopher protocol is described in RFC 1436 [RFC1436] and
   supports items and collections of items (directories).  The Gopher+
   protocol is a set of upward-compatible extensions to the base Gopher
   protocol and is described in [Gopher+].  Gopher+ supports associating

   arbitrary sets of attributes and alternate data representations with
   Gopher items.  Gopher URLs accommodate both Gopher and Gopher+ items
   and item attributes.

   Historical note: The Gopher protocol was widely implemented in the
   early 1990s, but few Gopher servers are in use today.

2.1.  Gopher URL Syntax

   A Gopher URL takes the form:

      gopher://<host>:<port>/<gopher-path>

   where <gopher-path> is one of:

      <gophertype><selector>
      <gophertype><selector>%09<search>
      <gophertype><selector>%09<search>%09<gopher+_string>

   If :<port> is omitted, the port defaults to 70. <gophertype> is a
   single-character field to denote the Gopher type of the resource to
   which the URL...
