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 WEBCOOKIES(4) WEBCOOKIES(4) (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. Hget(1) uses /mnt/webcookies/http, when it exists, to manage cookie state. Webfs does not (yet). SOURCE /sys/src/cmd/webcookies.c SEE ALSO hget(1) BUGS It's not clear what the relationship between cookiefs and something like webfs should be.
