Long (>~3k) POSTED fields get truncated

Following test produces correct results (twice the same length) on Linux + Apache + PHP, Windows NT + IIS + PHP,
but NOT on Windows NT + Apache + PHP.
In last case, back in PHP the length appears to be 4374
bytes. Making the fieldname longer or shorter affects
this length, adding more fields doesn't.

This behaviour looks very much like reported bug #18961,
which is closed. Today, I downloaded, the what I think is,  the latest version (4.4.0-dev). But problem still exists.

The apache server I use is Apache: 1.3.19.0.0a delivered with Oracle Application Server 1.0.2.2.2a .

My test file:

<?php
  if(isset($_POST['data1']))
  {
	echo "<html><body>Data length: " . strlen($_POST['data1']) . "</body></html>";
        return;
  }
?>
<html>
<body>
<?php echo "<form name='form' action='$PHP_SELF' method='post'>"; ?>

<input name="data1" type="hidden" id="data1"/>
</form>
<script language="JavaScript">
   var data = document.getElementById("data1");

   data.value = "<?php echo str_pad('', 6000, 'x'); ?>";
   alert("Datalength: " + data.value.length);
   form.submit();
</script>
</body>
</html>

Thanks,

Are you sure you have replaced ALL the old files with the new ones found in the package? Most important one being php4ts.dll (and also make sure you don't have many copies of it!)

I double checked it, found the file you mentioned twice, but both are the same, new updated files.
So problem persists.

Indeed,

we changed our server into RedHat 8.0 (Apache 2.0, PHP 4.2.2).

PHP Code that worked fine on the old server doesn't work on the new server. Post-method forms let some variables (small) pass without any problem, but bigger vars got truncated and concatenated with the original value.
