you don't have to. apache does it for you.

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.
