I have seen reference to setting the header:
X-Accel-Buffering: no
when streaming files back through nginx. Is this something you may add to your library.

• ability to store a filename different from source (from OpenFile)

• ability to return the headers instead of using header() function ; with psr objects, you have to use $response->withHeader() function.

Steps to reproduce
Try to example code in "Getting Started" to create an archive with one files add in chunks

require_once "support/zip_stream_writer.php";

ZipStreamWriter::StartHTTPResponse("test.zip");

$zip = new ZipStreamWriter();
$zip->Init();

$lastmodified  = mktime(0,1,0);
$lastaccessed = $lastmodified + 60;
$created = $lastmodified - 24 * 60 * 60;

$options = array(
    "last_modified" => $lastmodified,
    "64bit" => true,
    "unix_attrs" => 0644,
    "extra_fields" => array(),
    "comment" => "Best file ever."
);

ZipStreamWriter::AppendNTFSExtraField($options["extra_fields"], $lastmodified, $lastaccessed, $created);

$uid = 1234;
$gid = 1234;
ZipStreamWriter::AppendUNIXExtraField($options["extra_fields"], $lastaccessed, $lastmodified, $uid, $gid);

$zip->OpenFile("Hello2.txt", $options, 0);
$zip->AppendFileData("Hello ");
if ($zip->BytesAvailable() > 65536)  echo $zip->Read();
$zip->AppendFileData("there!");
echo $zip->Read();
$zip->CloseFile();
echo $zip->Read();

$zip->Finalize();
echo $zip->Read();

And running WinZip to try opening it.

Actual behavior
If you try to open it in WinZip, apparently the ZIP file header is readable, but extracting at least some files fails like this:

I am looking for advice on how to track down this problem. I try to generate the archive with and without 64bit with same result.
This problem doesn't exist with AddFileFromString method.

Version of ZipStreamWriter for PHP
master

Thanks for your help looking into this.
