Use a content delivery network (CDN) or something like Amazon S3. CDNs are usually targeted at large-scale anonymous access, which is not quite what you want. S3, on the other hand, is private by default, and can easily be accessed by secured URLs that are only accessible for a narrow window of time. So someone requests your asset, and instead of serving it with CFCONTENT, you redirect them to S3 with a URL that's only good for a handful seconds. I do this for a few different things, and it works like a charm. It also offloads the bandwidth from my infrastructure to Amazon's.
You might be able to synthesize something like this with IIS, as well. It won't server a given asset unless it has some one-time or short-lived token attached to the URL. Set that up to protect your downloads, and then do the same compute token/redirect thing to your own IIS server and let it serve the file instead of CF. cheers, barneyb On Mon, Jun 9, 2008 at 11:50 AM, George Abraham <[EMAIL PROTECTED]> wrote: > Hi all, > CFMX 7 Enterprise on IIS and Win 2003.
