"Do i must provide here code that allow downloads for files till 8Gb
with multiple threads and resume support, witch is working under unix
cgi, and not under win32 sapi?"



No, thanks.



Does it work with apache on unix as well? If yes, is it a 64bit or 32bit
machine?



The problem could be still the 32bit limitation as the apache2 SAPI
replaces the headers with the correct length using strtol, which
converts a string to a long. A long is always 32bit on Windows.



I will check that code, needs some tweak on Windows (no luck I think on
unix 32bit).

The problem is not in the filesize. Headers was checked with the latest
wireshark. Under the cgi i receive correct header. Under sapi not. Do i
must provide here code that allow downloads for files till 8Gb with
multiple threads and resume support, witch is working under unix cgi,
and not under win32 sapi? I redused test case to exactly minimum amount
of code needed to reproduce error.

The header is correctly sent without modification (you can verify that
using cgi in the console). However PHP does not support large file
support and only 2^31 bytes are read and sent.



There is already a feature request for LFS > mark this one as duplicated
(bogus).

Description:
------------
Content-length header is limited to 32bit integer on wista 32 systems
under apache 2 sapi.

header("Content-Length: 2967901695");

Expected on client - Content-Length: 2967901695

            Actual - Content-Length: 2147483647

Test script:
---------------
<?php

header($_SERVER['SERVER_PROTOCOL'].' 200 OK');

header('Accept-Ranges: bytes');

header('Content-Type: application/octet-stream');

header('Content-Disposition: attachment; filename=test.txt');

header("Content-Transfer-Encoding: binary");

header("Content-Length: 2967901695");

header('Connection: close');

//we open file with size exactly 2967901695 bytes

$fp = fopen("somefile.name", 'rb');

fpassthru($fp);

?>

Expected result:
----------------
Content-Length: 2967901695

Actual result:
--------------
Content-Length: 2147483647
