I have one project.

I have a html document displaying swf file. That's fine. But the swf file ALSO GETS STORED IN USER'S INTERNET CACHE. So, when anybody tries visiting the full url of the swf file, they can download it to their desktop. I already have a watermark within the swf file, but flash experts can separate the watermark from the swf file easily.

So:
Does anybody know how to prevent the swf file from being downloaded, especially given that the swf file can be stored in user's internet cache inevitably, when users view the html document?

Note: .htaccess has already been modified, but that doesn't prevent the file being stored in user's internet cache, so it is still downloadable as a result, due to internet cache's storage.

ANYBODY HAS A SOLUTION ?

FOR YOUR TESTING PURPOSE and PROOF of results:

I have provided a zip folder. For those who prove they can ACHIEVE THIS RESULTS (i) and (ii), I will SELECT HIS BID

---------------

The Golf_Demo_images.html and images folder should be uploaded to a public_html folder on your server's own site. The Golf_Demo_images.html should display successfully on http://www.yourdomain.com/Golf_Demo_images.html , without watermark on any images and swf. This is (ii).

But upon viewing just the swf files' or graphics FULL URL, ie http://www.yourdomain.com/images/Golf_Demo1.swf or http://www.yourdomain.com/images/Picture2.jpg, etc ... watermark should be in front of these. This is (i).
User should NOT be able to separate the watermark and this.

Everything needed is already included in the zip folder called Test_on_your_server.zip.
WHOEVER SUCCEEDS IN SHOWING PROOF, I WILL SELECT HIS PROJECT BID !!! LASTLY, PLEASE DON'T MAKE ANY INSANE BIDS EXCEEDING $100 FOR THIS. An example is the bid that is $777

I know programmers who bid researched that I have paid a lot of money for a small task to another programmer recently, but that's because we have projects OUTSIDE OF SCRIPTLANCE, AND I PAY HIM AT THE SAME TIME FOR SEVERAL OTHER TASKS.

So, KINDLY NOT MISUNDERSTAND AND THINK THAT I WILL PAY AND SELECT INSANE BIDS for TRIVIAL TASK LIKE THIS!
