I'd guess one of two things (but i'm usually wrong about this stuff.)
	a_ there might be some sort of redirect limiter config option.  i  
know a few MTAs have something like that when redirecting an email  
address to avoid endless loops.
	b_ maybe it has something to do with the footnote at that registry  
			note that this example differs from the Registry example only in  
that it does not attempt to fiddle with $r->status() -  
ModPerl::Registry uses $r->status() as a hack, but handlers should  
never manipulate the status field in the request record.

		that sounds to me like it has to do with the nature of the redirect  
as an internal subrequest and not an external one.   i'm only  
speculating, but i think the subrequest is a nested request like this:
				possible implemetation
				 	request 		{
				and that anything not fatal is essentially ok
				that would be dissimilar to it being a 'startover' with a new url  
like this:

				possible implemetation
					 request 		{

in either case, if someone who works on the internals could clarify  
that, i've been wondering this for a while.

the naming of the api and placement of methods, to me, is really  
awkward - subrequest suggests that its an entirely new request nested  
in $r (which, judging by the rest of the class methods, it seems to  
be )  but having internal_redirect in there suggests that its a  
redirect and startover for the parent request.   in sure there is a  
very good reason why redirect is in subrequest and not request -  
could someone point me to a url where i can read up?

in any event, i'd look into $r->is_initial_req 

and try something like  that recipe to subrequests only.
