Subject: Disabling the built-in POST handler
From: stef@noc.uoa.gr ("Stefanos Stamatis")

Trying to find a way to disable the built-in post form handler
for the reasons discussed here:
http://marc.info/?l=php-general&m=119160177617046&w=2
I looked at the code of php and found out that inside main/rfc1867.c in
function rfc1867_post_handler there is a check whether the posted data
content length exceeds the post_max_size parameter.
If so it aborts the function (with a warning).

(php-5.2.4, main/rfc1867.c, line 798)

        if (SG(request_info).content_length > SG(post_max_size)) {
                sapi_module.sapi_error(E_WARNING, "POST Content-Length of
%ld bytes exceeds the limit of %ld bytes",
SG(request_info).content_leng
th, SG(post_max_size));
                return;
        }

So setting post_max_size to zero for the script with php_value in the
apache configuration disables the built-in post form handler resulting in
the desired behaviour!

My question is whether this is the expected behavior of php that we can
count on and can be used as a solution to our problem.

Thanks in advance,
Stefanos Stamatis.
