Cache Sortable Position

Cache Sortable Position


Hello,
I'm in the beginning stages of deciding what UI components I want to
bring into a project at work and one of them was allowing users to
drag different components around and have them stay in that position
during their session and to cache them. I think this is more of a
server side question with sessions and caches but does anyone have any
information on how to achieve this or any references.
Thanks
