session_write_close() worked as a lifesaver for me when automatically uploading files to a user
(forcing a download instead of a link). If files are large, and since session_start() does not allow
another page using session_start() to proceed until it's done, i was not able to upload more
than one file at a time. By using session_write_close() before beginning the file upload, my users
can now download as many big files as they like, at the same time. Example:
<?
session_start();
/* Do session stuff here; security; logging; etc. */
session_write_close();
/* NOW write out the requested file. */
header("Content-type: audio/x-mpeg"); /* or whatever type */
header("Content-Disposition: attachment; filename=" . $filename);
header("Content-Length: " . $filesize);
header("Content-Transfer-Encoding: binary\n\n");
header("Pragma: no-cache");
header("Expires: 0");
$file_contents = file_get_contents($filepath);
print($file_contents);
?>
