Google App Engine map /foo to / - google-app-engine

Question

I have this web app and the very first page that loads is the login page:
app.appspot.com
after successfully login the app redirects to:
app.appspot.com\foo
I'd like to know if there is a way to map
app.appspot.com\foo to app.appspot.com
UPDATE
Here's my app.yaml:
handlers:
- url: /js
static_dir: static/js
- url: /css
static_dir: static/css
- url: /fonts
static_dir: static/fonts
- url: /img
static_dir: static/img
- url: .*
script: handler.app
secure: always

This answer assumes you're using the python environment.
You could have a login_required decorator to check if the user is logged in, redirect to a login page if not and then back after login completes. An example of such decorator which uses the GAE users API as authentication method can be found in webapp2_extras.appengine.users:
from google.appengine.api import users
def login_required(handler_method):
"""A decorator to require that a user be logged in to access a handler.
To use it, decorate your get() method like this::
#login_required
def get(self):
user = users.get_current_user(self)
self.response.out.write('Hello, ' + user.nickname())
We will redirect to a login page if the user is not logged in. We always
redirect to the request URI, and Google Accounts only redirects back as
a GET request, so this should not be used for POSTs.
"""
def check_login(self, *args, **kwargs):
if self.request.method != 'GET':
self.abort(400,
detail='The login_required decorator '
'can only be used for GET requests.')
user = users.get_current_user()
if not user:
return self.redirect(users.create_login_url(self.request.url))
else:
handler_method(self, *args, **kwargs)
return check_login
You could map your handler currently handling the '/foo' path to '/' and apply such decorator to its get() method, obtaining the result you desire (your decorator would actually perform the login function by your '/' current handler).
And you can apply such decorator to any other handler/path in your app.
