DECLINE, ERRORs in the middle of hanlers stack

["Ruslan U. Zakirov" <cu...@wr.miee.ru>]

        Hello All!
"Stacked handlers" is a very useful technology, but as I think incomplete.
I need some suggestions.
My project split content handler in the few parts. And each handler
send part of the requested page to user, but sometimes I must stop
proccessing and return DECLINE, redirect user or return some ERROR.
Error appear in the middle of the page.
I want Apache to buffer content and send it after last handler in
chain return OK. Is it possible?
      Beforehead thanks, Ruslan.

Sure, you can buffer the data using $r->notes or $r->pnotes and have the last 
handler send it out. But instead of stuffing the content there, you are 
probably better off (more efficient?) to create a buffering class, instantiate 
an instance, and store it in $r->pnotes between invocations.
