Re: subrequest->run() doesn't send HTTP headers

Hello list,

i'm trying to run a subrequest from within

headers are sent (even so the documentation
from 'Writing Apache Modules' claims that 'run()' 
  
                                  "... will do

  "... you must not send the HTTP header and

well, the Eagle book is a little out of date here

subrequests do not include headers, so if you use $sub->run() to send the 
subrequest to the client you are required to send headers yourself.

to alter this behavior, use $sub->run(1).

Here's a short test case:

sub handler {
  my $req = shift;
  my $filename = "/tmp/sample.html";

  my $sub = $req->lookup_file($filename);
  $status = $sub->status;
  if($status == 200)
    {
      $ret = $sub->run;
    }
   return ret;
}
Furthermore, if the filename given to 'lookup_uri()'
points to a directory, $sub->status will return '200'
but '$sub->run()' will return '301' (which is o.k. since
the filename should end with a '/' ...).
Any ideas?
