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, webcookies 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
values 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 connecting
to a web server at that IP address. If domain is a pattern beginning
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=versionThe version of the HTTP cookie specification, 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 conform 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 currently 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 webcookies decides not
to accept the cookie (as outlined in RFC2109, section 4.3.4),
no indication is given.
