I am not sure this is relevant to the discussion but:
Your proxy trick will not work to access resources from "local machines" within a client's NAT. The flash player could potentially access those since it is already located behind the NAT. What I mean is that the flash player might have network access to some non-internet-public stuff. B. 2006/7/22, Paul Neave <[EMAIL PROTECTED]>:

I don't see the point of restricting access to BitmapData from another server when all you have to do to get at it is use a proxy script on your own server. Here's an example: http://www.neave.com/temp/proxy.php?proxy_url=http://www.google.com/intl/en/images/logo.gif The image looks as though it's coming from my server but it's actually coming from a domain I don't have server-side access to. So from Flash's point of view, there's no security risk. In AS3: var request:URLRequest = new URLRequest("http://www.google.com/intl/en/images/logo.gif";); var loader:Loader = new Loader(); loader.load(request); addChild(loader); would work fine, but I can't use BitmapData methods on the image. If I replace the URL with the proxied one above, I'd be able to use BitmapData without any problem. As far as I can see, any potential "hacker" could use a proxy script like this so I don't see what security benefit there is apart from just annoying developers! I'm now left with two options: 1) either proxy the image so I can access BitmapData (which costs me bandwidth and is much slower than direct access, especially if you're accessing many images at once) or 2) don't use BitmapData and put up with having the images pixelated when scaled or rotated. Either way it doesn't make me happy :( Paul. _______________________________________________ [email protected] To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
