captch & sessions

[eluser]shmoula[/eluser]
Hey, i think i got it! When i woke up this morning, think came :-D.
So, im trying to write to the same variable, from which im reading at the same request. That is the problem, there must exist some mechanism, which cleans up that variable before next request. So i see solution in that - to use "normal" session and after use just clean that up and set again, or generate random name for that flashdata. (or use standard way via database ;-)).

So i think, my problem is solved, im gonna to test it out!
