What really happens is that flex requests thr rsl with some digest. If the player already cached that rsl it uses the cached version and does not download over the network.
If not cached, the digest confirms the bits haven't been tampered before storing in the cache ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Gregor Kiddie Sent: Friday, November 09, 2007 12:41 AM To: [email protected] Subject: RE: [flexcoders] RSL Digests. Hah! Fair point. Would it be less secure to just download the swf's digest and test that against the digest for the swf already cached, and then choosing whether whether to download the remote swf? Actually, thinking about it, as catalog.xml is part of the swc, it's probably not possible to only download it without grabbing the rest of it too. That seems a little wasteful to me. Gk.

I can double check, but how would you compute the digest w/o getting the bytes first? ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Gregor Kiddie Sent: Thursday, November 08, 2007 3:31 AM To: [email protected] Subject: [flexcoders] RSL Digests. Checking out this page : http://livedocs.adobe.com/labs/flex3/html/help.html?content=rsl_08.html <http://livedocs.adobe.com/labs/flex3/html/help.html?content=rsl_08.html > We like this feature as it gives us a lot of control over which version of a swf we can deliver to a client, but there is a couple of points the article doesn't make clear. Does the RSL get downloaded onto a user's machine before the digest is checked? I wouldn't imagine so, as this would be a huge waste of resources (especially for those of us tossing around massive swfs). So, does the digest get checked against before, or after the RSL is downloaded? Gk.
