I have an script that receives an encrypted url and from that generates a download, the most critic par of the script is this:

$MimeType = new MimeType(); $mimetype = $MimeType->getType($filename); $basename = basename($filename); header('Content-type: $mimetype'); header('Content-Disposition: attachment; filename=\'$basename\''); header('Content-Length: '. filesize($filename)); if ( @readfile($filename)===false ) {   header('HTTP/1.0 500 Internal Server Error');   loadErrorPage('500'); }

Downloads works as charm in any Browser except IE, I have seen problems related to ‘no-cache’ headers but I don’t send anything like that, they talk about utf-8 characters, but there is not any utf-8 characters(and the $filename has not any utf-8 characteres neither).

  1. This site has a problem similar to yours in IE6. To summarize:

    session_start() by default sends a cache control header including ‘no-store’. Internet Explorer takes this a bit too literally, but doesn’t have appropriate error handling for the case, and as a result explodes cryptically when you attempt to save the output page to disk.

    Before session_start(), add ‘session_cache_limiter(‘none’);’, or look up that function and tweak the limiter as appropriate (probably ‘private’ is closer to the mark).

    I realize the code snippet you posted does not include a call to session_start();, but I figured I’d share this possible solution in case you do have a call to it and just didn’t show us.
