Headers Sent Twice

Hi All,

Here's a patch against ApacheHandler to keep it from sending headers 
during an abort or redirect when they've already been sent. I ran into 
this for when I've got a callback that sends content to the browser 
before it aborts (and this is before a request object is created).

+++ ApacheHandler.pm	Fri Apr 30 18:48:30 2004

  		     rethrow_exception $err;

  	return $retval;
      }

Thanks,

David
