Re: Persistance of ColdFusion Structures
Not arguing. Just saying there are ways to save a struct into a cookie. Yes, it's not technically a struct anymore...just a string representation thereof, and yes, it needs to be deserialized back...but wanted to make the point that it -can- be done (even if in a roundabout way) :) On 6/21/06, Everett, Al (NIH/NIGMS) [C] <[EMAIL PROTECTED]> wrote: > Yes, you can, but then it's not REALLY a structure any more, is it?

Yes, you can, but then it's not REALLY a structure any more, is it? It's a string at that point. It needs to be deserialized to be used, and then it's back to being in a different scope.
