How to have a "random" order on a set of objects with paging in Django?

I have a model with 100 or so entries - the client would like these entries to appear in a 'random' order, but would also like paging in there.

def my_view(request):
  object_list = Object.objects.all().order_by('?')
  paginator = Paginator(object_list, 10)
  page = 1 # or whatever page we have
  display_list = paginator.page(page)
  ....

So my question should really be - how can I have my object_list created once per user session?
