If your website is hosted on one computer say
http://server1.com/yoursite and you have other files on a computer that also has an ip address or a DNS name, than just link to your files from the main site to the secondary site like this: < a href="http://Example2/ExampleProgram.exe">Text</a>
<edit> OK... so after re-reading the thread is your problem not knowing how to edit the apache config file? </>
