I still have the impression you are putting the cart before the

Let me make a few assumptions about the typical web site, and see
what implications I can infer:

* your site will have multiple subpages with different content per

* all content pages require a viewer to be "logged in" (have a valid
session cookie, or whatever the authentication scheme uses)

* session cookies have some expiration time

* users (who are out of your control) can bookmark any subpage URL in
order to return to that page quickly, bypassing any site navigation

=> ANY page URL might be requested by someone who does not have a
current/valid authentication session cookie

This means that handlers for all "normal" content pages must include
the ability to redirect non-authenticated users to a "log in" page; and
to be friendly, after a valid log-in, that page should return them to
the URL they initially requested and not some top-level of your site.

Since all pages need to handle this action, making the root of the
web site a log-in/registration page is somewhat futile (besides which,
if a user WITH a session cookie reenters your root URL, your "log in"
page is going to have to detect that cookie and redirect to some other
top-level page).

Also note that my prior response never said that your page would
redirect to a registration page. Rather it was that the log-in page
would have a button or link /to/ a registration page for new users.
Otherwise you end up with a log-in page handler that has to
differentiate between a log-in and a registration.

sessionkey = None
if username and password:
if validate(username, password):
sessionkey = newcookie()
if allregistrationdatasupplied(*args):
if noconflict(newusername):
sessionkey = newcookie()

if sessionkey:
#return top-level page and session cookie
#redisplay log-in/registration page with added error message
