Restricting Download speed on attachements.

At this point in time, if one is to download an attachement from our forums he will be able to use up all of the line as long as his internet connections allows him to.

What i was wondering, is it possibly to put a restriction on mysql attachemnts so that users can only download at say a maximum speed of 30k/s instead of the 200k/s they are getting ?

Thanx you

File attachment.php, at the very end

Replace

PHP Code:


		
			
echo $attachmentinfo["$imagetype"];

With

PHP Code:


		
			
// UploadBandwithLimitHack

// Original line: echo $attachmentinfo["$imagetype"];

$bandwidth = 30; // Desired max. bandwidth in KB/s.

$i = 0;

while ($i < strlen($attachmentinfo["$imagetype"])) {

  echo substr($attachmentinfo["$imagetype"], $i, 1024);

  $i += 1024;

  flush();

  usleep(1000000/$bandwidth);

}

// UploadBandwidthLimitHack

This might help, but isn't a good solution IMHO.

Quickly looking at the code I'd assume it works for images only.

That's what i assumed as well.

Which is not good for me. i need ti to essentially effect all attachements.

Any ideas from the gurus here?
