Internal redirect from an output filter (Apache2.x)

[Sumeet Singh]

Hi,
   I was wondering if invoking an internal-redirect from within an 
output filter is legal. I need to do that from my output filter but want 
to make sure that it conforms to apache2.0 API before I go ahead and 
design/code it.

thanks,

p.s.
   http_header_filter actually does that (indirectly) by invoking 
ap_die while processing an error_bucket. ap_die will call 
internal-redirect if the corresponding custom error response 
(ErrorDocument) is a url.
