X-SendFile feature

Most modern web servers provide the X-SendFile feature: they take control over the process of sending a file to the client. Your application, for example, may check permissions, set some headers, like Content-Disposition, and then delegate the hard stuff to web server.

Refer to the documentation of your favorite web server for more information.
