How to count download?

[inside7]

I use vBulletin Forum and limit the number of downloads per day attachment of members by the number of times to download attachments. I have done, but that problem is as follows:

my query code:

if (defined('count_download')) { $db->query_write(" INSERT INTO " . TABLE_PREFIX . "attachment_limit (attachment_limit_userid, attachment_limit_date) VALUES ('".$vbulletin->userinfo['userid']."', '".TIMENOW."') "); }

When I download an attachment in your browser, then write the query to the data as follows:

When I download an attachment by IDM, DAM, FlashGet, write queries on the data as follows:

This means that at one time to download but when downloaded by the browser and download the IDM program is different!

Is there any way to download attachments with IDM, DAM .. they are the same as download attachments in my browser?
