Streaming a PDF file to the user`s browser will help in adding an 
authentication mechanism. 

A script file can be called to stream the PDF file. This script should 
authenticate the user based upon the credentials supplied. Also, this script 
can add cache-control headers, which will prevent the PDF file being stored in 
the local cache on the user's machine.

A whitepaper discussing these issues is available at
