 IMO a better version:

 cookies "foo" and "bar" are removed

 if (req.http.Cookie) {
                 set req.http.Cookie = regsuball(req.http.Cookie, "(^|; )
 *[foo|bar]=[^;]+;? *", "\1");
                 set req.http.Cookie = regsub(req.http.Cookie, "[; ]*$",
 "");

                 if (req.http.Cookie == "") {
                         remove req.http.Cookie;
                 }
 }
