Here is a sample code do what you wanted.
app = web.application(urls, globals())
def login_processor(handler):
# web.ctx.path contains the current path requested
if is_secret(web.ctx.path) and get_user() is None:
raise web.seeother('/login?redirect=' + web.ctx.path)
else:
return handler()
you can fill in the details.
is_secret check if the give path requires login permissions.
get_user returns the name of currently logged in user or None.
I'm assuming that login is at /login and it takes optional redirect
argument which is used to redirect the user back to that page after
login.
