Okay, I found a solution to part one of my questions by changing my headers,
but for some reason I am still getting a fractional download of the file.
Most commonly it's about 16.6KB of a 4MB file. The kicker is it says that it
completed successfully.
Here is the modified code:
<?php
$download = 'url/path/to/file'.urldecode( $_GET['link'] );
$type = urldecode( $_GET['type'] );
$size = filesize( '/abs/path/to/file'.urldecode( $_GET['link'] ) );
header("Pragma: public");
header("Expires: 0"); // set expiration time
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
// browser must download file from server instead of cache
// force download dialog
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
// use the Content-Disposition header to supply a recommended filename
and
// force the browser to display the save dialog.
header("Content-Disposition: attachment;
filename=".basename($download).";");
/*
The Content-transfer-encoding header should be binary, since the file
will be read
directly from the disk and the raw bytes passed to the downloading
computer.
The Content-length header is useful to set for downloads. The browser
will be able to
show a progress meter as a file downloads. The content-lenght can be
determines by
filesize function returns the size of a file.
*/
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".(string)($size));
readfile("$download");
