.SH ARGUMENTS
cgi - a CGI struct
.br
name - the cookie name to clear
.br
domain - the domain to clear, NULL for none
.br
path - the cookie's path

.SH DESCRIPTION
cgi_cookie_clear will send back a Set-Cookie string that
will attempt to stop a browser from continuing to send
back a cookie.  Note that the cookie has to match in
name, domain, and path, and the luck of the Irish has to
be with you for this work all the time, but at the least
it will make the browser send back a cookie with no
value, which the ClearSilver cookie parsing code will
ignore.

.SH "RETURN VALUE"
