I haven't looked at your problem in detail (I seldom read this group
anymore) but I think you want something like:
def index( page='myhomepage' ):
If the function gets called via the "/" url, there will be no 'page'
argument so you need to write the function signature to make that
argument optional.
No idea about question #2.
