New Comment:
Testing with that script fragment (as the entire web-page), I get the
following for output:
------------ SNIP -------------
HTTP/1.1 200 OK^M
Date: Thu, 21 Aug 2003 01:28:13 GMT^M
Server: Apache/1.3.27 Ben-SSL/1.48^M
Connection-Type: Keep-Alive^M
Content-Length: 0^M
Content-Type: text/html^M
^M
------------ SNIP -------------
I assume this is correct. I displayed the CR's (I'm on UNIX).
Apache 1.3.x doesn't support HTTP/1.1 style connections?
In Apache 1.1 and 1.2 documentation, I see:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Enabling Keep-Alive Support
Apache 1.1 comes with Keep-Alive support on by default, however there
are some directives you can use to modify Apache's behavior:
Note: Apache 1.2 uses a different syntax for the KeepAlive directive.
<<<<<<<<<<<<<<<<<<<<<<<<<<<<
I am *NOT* using PHP built as a CGI SAPI - it's a statically linked
MODULE built into Apache-SSL.

What if eliminating the following line?
header("Connection-Type: Keep-Alive");
Note that HTTP/1.1 style connection is not supported in either Apache 1
or CGI SAPI.
And also try to generate a null output and see how it'll work:
<?php
header("Connection-Type: Keep-Alive");
header('Content-Length: 0');
?>

Description:
------------
Very straightforward.
I have a preamble and postamble include on ALL of my main .php pages...
which use ADODB session management, some PEAR, and other typical
dynaweb goodies.
The Content-Length header is *ALWAYS* off by about 81 bytes, as in, the
ob_get_length() is always smaller than the actual size of the content
sent...
I've verified this with "netcat" - after trimming the headers from the
reply, the content is 81 bytes larger than advertised in the
Content-Length header.
I observed no change in behaviour after adding the ob_clean() call into
my header file.
OTHERWISE, things work fine.
What's the deal? Is Apache silently adding CRLF's?
I am NOT using the gzhandler or transparent compression here. This is
just straightforward output.

Reproduce code:
---------------
The code for all of my index.php's consist of the following:
<?PHP
include_once 'db_header.inc';
................
include_once 'db_footer.inc';
?>
db_header.inc:
<?php
$start_time=gettimeofday();
ob_clean(); // paranoid and desperate
ob_start();
header("Connection-Type: Keep-Alive");
?>
db_footer.inc contains:
<?PHP
if ($LOGGING)
{
$LOG->close();
$LOGGING=FALSE;
}
header('Content-Length: ' . ob_get_length());
ob_end_flush();
?>
Note: there are no blank lines at the beginning of my *.inc or *.php
files.
Expected result:
----------------
I would expect Content-Length to reflect the actual output size.
