Your answers appears as a fresh posting to many regular usenet (as in
n-=gg). Not in theright thread, but as a new top posting. I understand
that the former version does it right.)
To your question:
I think the manual is very clear:
"The shutdown functions are called as the part of the request so that
it's possible to send the output from them. There is currently no way to
process the data with output buffering functions in the shutdown function. "
So no, you cannot use your output buffering.
It is hard for me to help you with the 200 and 500 headers without
seeing the whole set-up: Where do the possible errors arise?
Are you using custum errorhandler routines? If so, how do they look?
Are you handling only errors or also exceptions?
And many more questions. :-)
However, I can tell you how I debug in difficult situations (eg, INSIDE
the errorhandler): create a simple function that appends to a file, or
sends you an email. Add a timestamp to the message.
something like:
function debug($someMessage){
// add timestamp and email to yourself, or append to some file.
}
Then, from places that are otherwise hard to debug, use that function.
I wasted many days before I started using that approach. ;-)
Sorry I cannot be of more help. Maybe somebody else can.
Good luck.

Erwin Moller
