Weird response from both CGI and modperl handlers

Hi people,

I've got some problem with both cgi and modperl.
when I post something to /perl/test.pl which just print header and a 
string I got some strange numbers. The post is done with a php script.

test.pl :

use strict;
use CGI qw/:standard/;

print header;
print("\ncoucou\n");

and below is the response the php script got :

HTTP/1.1 200 OKDate: Tue, 19 Jun 2007 21:39:55 GMTServer: Apache/2.2.3 
(Ubuntu) mod_ssl/2.2.3 OpenSSL/0.9.8c mod_apreq2-20051231/2.6.0 
mod_perl/2.0.2 Perl/v5.8.8Connection: closeTransfer-Encoding: 
chunkedContent-Type: text/html; charset=ISO-8859-18coucou0

It got 8coucou0 instead of coucou.

The issue is that I can't modify the php script which works for other 
customers and this script can't do what it has to because of these two 
more numbers in the response.

for guys who speak php here is the code that post data to /perl/test.pl :

$fd = fsockopen("ssl://".$this->server,443, $errno,$errstr, 60) or 
die("No way to open");
fputs($fd, "POST /perl/test.pl HTTP/1.1\r\n");
fputs ($fd, "Host: ".$this->server."\r\n");
fputs($fd, "Content-type: application/x-www-form-urlencoded\r\n");
fputs ($fd, "Content-length: ".strlen ($fluxsms)."\r\n");
fputs ($fd, "Connection: close\r\n\r\n");
fputs ($fd, $data);
$response = "";
while (!feof ($fd) )
{ $response = $response.fgets($fd, 128); }
fclose($fd);

thanks.

Great. It works :-) when using $r->ser_content_length()

thanks.

Add a Content-Length output header and avoid output filters that can change 
the content length.

Or use HTTP/1.0

Are we able to disable the chunk transfer ? To send all in one shot ?

because your php script is not handling the chunked transfer encoding
properly.

  http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.6.1

presumably php has some http-specific libraries for POSTing requests so
that all this low-level stuff becomes stuff you don't need to worry about.
