Permissions on files? Avoid linking?

[stryka]

Using the VB userDB.. how do I implement a permission system based on a file....

Here's what I mean... i would like to create a member's only audio/video section on a Non-VB page that contains permissions. To access the page it will check if you are a member....

BUT>>> HOW do you avoid unregistered users from directly linking to the specific file since the a/v files will be on my server?

NOTE: I would like my members to be able to directly link to the files from a post within the msg board... but I don't want anyone to link directly from outside of the main site...

Thanx in advance!
