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.
