When a request comes in $r->main and $r->prev are false. If it issues a subrequest $subrequest->main keeps $r so that the subrequest can modify the main one. Similar, if the main request is replaced by an internal_redirect() $redirectrequest->prev points to the main request in case you need something from there. Torsten
