There's nothing you can do about the O/S swapping out the region of RAM with your data in to disk, and having that stay there after the process exits. It depends on the threat profile you are defending against, though, as to if this matters. Worse case, your end users are all evil, and run your application in a virtual machine, pause it at the crucial moment and parse the memory dump. -- Tom Chiverton Helping to dramatically expedite proactive services On: http://thefalken.livejournal.com This email is sent for and on behalf of Halliwells LLP.

As a follow-up... I am not writing this to disk myself. I am using an HTTPService to download the file, then processing it in memory into a data-store. Never (by me) is either the downloaded file, nor the data-store intentionally written to disk. I think, because of this, the two files being written I am concerned about (cache) are temporary internet files and normal swap-like disk caching.

Is this configurable? Encryptable? I've been digging but all the cache info I find is about the swf file itself. Thanks!
RE: [flexcoders] Re: Flex Caching Data?
Have you looked in the browser temporary files folder to see if it has turned up there? I think that's the only place it'll be stored. I don't think Flash does any caching, it just relies on the browser cache.
