Django: Why can't I get my development server to work?

I'm on Windows XP with the latest install of Python 2.6 (and the development server has been working up until last night). I have the path and Python path stuff all set up, and my dev server has worked forever. I recently replaced my django-trunk with a new pull from the Django trunk. I thought maybe there was an import error or something that Django wouldn't catch in one of my app's models.py so I started a new project (empty but just for testing) and it still didn't work. I restarted my computer and tried the new empty app again python manage.py runserver 8080 and went to http://127.0.0.1:8080/ and it worked ("Congrats. Django is insta..."). So I CD over to my real project and tried again and it didn't work. I'm not getting a stack trace or anything like that. I either get [17/Ja/2010 16:30:51] "GET / HTTP/1.1" 301 0 as output when I visit http://127.0.0.1:8080/ in my CMD prompt or I get nothing (even if I hard refresh, etc). What could this be?

Update (Important):

Firefox tells me Firefox can't find the server at www.127.0.0.1. even though I'm at http://127.0.0.1:8080/. Does this mean that Django is really sending a 301 to www.127.0.0.1 for some other reason?

I removed PREPEND_WWW from settings.py, and even removed all the apps (except for the django admin and preset ones) that were installed in settings.py.

Update 2: It works in Safari! How can this be? It's like 开发者_C百科Firefox is getting some sort of 301 but Safari works just fine.

yep, 301 permanent redirect is remembered by firefox, i've been stuck once on that one, restarting or cleaning history/cache didn't help, so i just ran it on another port.

edit after commenting:

assuming you use some localhost_settings.py to setup your project locally and still want to www_redirect on the production website:

try:
    from localhost_settings import *
    PREPEND_WWW = False
except ImportError:
    PREPEND_WWW = True

i do it this way
