Description
I can not download files from Drupal, server running on https/ssl
- Using IE7
- Download method: Private - files are transferred by Drupal.
- Site accessed over https/ssl
IE can not download the file, apparently because it can not store files downloaded over https in the browser cache.
This issue is described in more detail in a 4.x bug report as well. http://drupal.org/node/163298
I think it is mentioned here as well
http://support.microsoft.com/kb/323308/en-us
The problem can be solved by sending custom headers to IE
#1
I think I've solved the problem by making changes in the file module, similar to the solution others have posted for drupal 4.x (se related bug report).
/**

* @param $source File to transfer.
* @param $headers An array of http headers to send along with file.

function file_transfer($source, $headers) {
ob_end_clean();
global $base_url; //********* added ************
foreach ($headers as $header) {
// To prevent HTTP header injection, we delete new lines that are
// not followed by a space or a tab.
// See http://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.2
$header = preg_replace('/\r?\n(?!\t| )/', '', $header);
drupal_set_header($header);
}
//*********** added *******************
if (preg_match('|^https://|', $base_url)) {
drupal_set_header('Cache-Control: private');
drupal_set_header('Pragma: private');

// Transfer file in 1024 byte chunks to save memory usage.
if ($fd = fopen($source, 'rb')) {
while (!feof($fd)) {
print fread($fd, 1024);
}
fclose($fd);

exit();
