Activex Document Server & Internet Explorer

I don't know how your application works but I recently wrote a download system  in php (download a file by specifying a key code in the querystring of the URL, all files on the webserver in a directory above httpdocs to prevent direct downloads).

That php code looks up the file associated with the provided key, sets up the http headers, mime-type etc, then sends the file data in chunks and I can track how much data has been sent in the server side code - I could notionally send that data to a client side object during the download if I wanted. But why bother - most browsers I know already monitor how much data has been received for a download and show progress automatically.

What I'm trying to get at is - it might be easier for you to monitor the download in server code while the server gives data to the client; create a mechanism to send progress messages to a bespoke client ActiveX object. Why isn't the inbuilt IE download progress bar sufficient for the users, its a standard part of the IE user interface?

Cheers,
