drag and drop: Severside-script needed in order remind changes and to meet customer needs


I would love to allow a very limited number of users of my password-
protected website to
use the drag and drop functionality in order to rate DIV-Layers
according to their own relevance-impressions...
But:
I cannot implement that as I do not yet know how to save the changes
on my server. AS: When the user reloads or revisits my page, the
rating he did put into order will be gone!
Will I need a Severside-script in order to remind the changes and to
meet my customers needs? Is there anybody with similar experiences?
greetings, Stefan!
