All these headers scare me -- I've found that if you add all these,
sooner or later, you run into some browser that didn't do it right
anyway.
You may want to look at an alternative K.I.S.S. approach (rant):

There was a discussion yesterday on php-internals regarding Apache/PHP
forcing the HTTP response to 1.1 even if the browser asked for 1.0.
Part of that discussion was a sub-discussion about how it ought to be
possible for a PHP developer to FORCE the response to be 1.0
If your response is 1.0, there would be no chunking, as I understand it.
So there may be an "answer" for you buried in that thread, or you may
want to weigh in on a real-world need for this feature.
