Description: ------------ When Text_Wiki is integrated in a site that allows a session id to be transmitted through urls the session id would also be sent to external sites through the referer by the users browser. This can be prevented by using a local or external derefer (http://en.wikipedia.org/wiki/Dereferer). For this all external urls like 'http://www.google.com' have to be translated to something like 'http://derefer.php?url=http://www.google.com'. AFAIK Text_Wiki does not support such a translation yet.

Maybe a render configuration key 'href' for the 'url' rule would be a solution: setRenderConf('xhtml', 'url', 'href', 'http://derefer.php?url=%s');
