Zend Download Server (ZDS)

Contents:

The Zend Download Server* is a PHP (Zend Engine) plug-in which efficiently deals with serving large downloads such as videos e.g. .mpeg files, binary products such as .exe and .msi files, and any other large files which are served over the HTTP protocol.

How it works:

The Download Server supports two modes of operation (both of which can be used together or separately according to your needs):

• Manual mode - The download is initiated by a PHP script using one simple PHP API function call. Not only does it allow you to serve files which aren't under your web server's document root but also it allows you to run logic such as access restriction checks before the download is started.

• Transparent mode - In your web server's configuration file you map the files you want to be sent through the efficient downloading mechanism to PHP, and the Zend Download Server will jump into action automatically and serve them.

*The Download Server is currently not applicable for Windows Operating Systems.
