[Catalyst] Saving redirect URL in flash not sticking through login process

[Eric Berg]

Thanks, Will.  That I figured that would work, but I thought that the =

flash was the right way to do it -- especially with the automatic =

cleanup, so I was holding off on trying that.

Why doesn't flash work across these multiple requests?  I thought that =

was the whole idea of flash vs. stash.
