WEBCOOKIES(4)                                       WEBCOOKIES(4)

     NAME
          webcookies - HTTP cookie manager

     SYNOPSIS
          webcookies [ -f cookiefile ] [ -m mtpt ] [ -s service ]

     DESCRIPTION
          Webcookies manages a set of HTTP cookies, which are used to
          associate HTTP requests with persistent state (such as user
          profiles) on many web servers.

          Webcookies reads cookiefile (default $home/lib/webcookies)
          and mounts itself at mtpt (default /mnt/webcookies).  If
          service is specified, cookiefs will post a service file
          descriptor in /srv/service.

          The cookie file contains one cookie per line; each cookie
          comprises some number of attr=value pairs.  Cookie
          attributes are:

          name=name           The name of the cookie on the remote
                              server.
          value=value         The value associated with that name on
                              the remote server.  The actual data
                              included when a cookie is sent back to
                              the server is ``name=value'' (where,
                              confusingly, name and value are the val-
                              ues associated with the name and value
                              attributes.
          domain=domain       The domain within which the cookie can
                              be used.  If domain is an IP address,
                              the cookie can only be used when con-
                              necting to a web server at that IP
                              address.  If domain is a pattern begin-
                              ning with a dot, the cookie can only be
                              used for servers whose name has domain
                              as a suffix.  For example, a cookie with
                              domain=.bell-labs.com may be used on the
                              web sites www.bell-labs.com and
                              www.research.bell-labs.com.
          path=path           The cookie can only be used for URLs
                              with a path (the part after
                              http://hostname) beginning with path.
          version=version     The version of the HTTP cookie specifi-
                              cation, specified by the server.
          comment=comment     A comment, specified by the server.
          expire=expire       The cookie expires at time expire, which
                              is a decimal number of seconds since the
                              epoch.
          secure=1            The cookie may only be used over secure

                              (https) connections.
          explicitdomain=1    The domain associated with this cookie
                              was set by the server (rather than
                              inferred from a URL).
          explicitpath=1      The path associated with this cookie was
                              set by the server (rather than inferred
                              from a URL).
          netscapestyle=1     The server presented the cookie in
                              ``Netscape style,'' which does not con-
                              form to the cookie standard, RFC2109.
                              It is assumed that when presenting the
                              cookie to the server, it must be sent
                              back in Netscape style as well.

          Webcookies serves a directory containing two files.  The
          first, cookies, is a textual representation of the cookie
          file, which can be edited to change the set of cookies cur-
          rently held.  The second, http, is intended to be used by
          HTTP clients to access cookies.  Upon opening http, the
          client must write a full URL to it.  After writing the URL,
          reading from the file will yield any HTTP Cookie: headers
          that should be included in the request for this particular
          URL.  Once the request has been made, any Set-Cookie: lines
          in the HTTP response header should be written to the file to
          save them for next time.  If cookiefs decides not to accept
          the cookie (as outlined in RFC2109, section 4.3.4), no indi-
          cation is given.
