sorry, I read too fast, this won't work with submitted swf's if you can't
get into them. Might try to see if you created a container swf that loaded
the submitted swf might work?
How about if you put a bit of actionscript in your swf to prevent it from
being displayed on any other url? It's not perfect - the swf can be broken
into and the code found, but it prevents regular surfers from grabbing the
swf and placing it on any other url, (including hot-linking to your swf from
another url), and also prevents viewing the swf if it is downloaded to a
hard drive.

Try loading/viewing this swf on any other url, or downloading and viewing
the swf from your hard drive. Just two frames of code, placed before your
real content.

(protectingbandwithfromother sites)
Hey,
Thanks for the tip..
We checked it out but what the way you adviced will be working with a
referer..
Meaning that the browser will give the last url to the server(/apache)..
Problem is that not all(/no) browser gives that var along with the request
Many thanks though.. any other thoughts?
Best Regards,
Dennis

I've only heard of this in regards to images, but it's termed hotlinking.
There's bound to be a bunch of solutions to it.

Subject: [Flashcoders] Loading Swf files in site (protecting bandwith
fromother sites)
We are trying to protect our swf-files from loading by others (protecting
our bandwidth).
Searching the net, no solution could be found for this. We want our users
flashfiles to be loaded from our site,
but rejected when called from other sites to secure our bandwidth.
NOTE: The flashfiles are submitted content, so we can't change them.
Does anyone have a suggestion on how to do this correctly?
-----------------------------------------------------
On a more technical note (for those that wish to know what we tried) :
- We tried PHP to parse the files, using an swf header. This works in
most
cases, but appearantly some swf files do not work
correctly (it looks fine at first, but things go bad when using the swf).
Even though the parsed file is both in Header
as in content equal (to the bit, checked that in filesize and in code)
the
code behaves differently than the
original swf.(for instance when a key is pressed a characters animation
will
play but won't be moved around).
- Now we'r trying to secure a webdirectory (with ModRewrite), to not load
swf files when not refered to by our site, but <object> and <embed>
tags do not pass on a referer in the header, thus blocking all requests
or
simple not blocking any.
Many Thanks
Dennis
