Django 1.4 form posting forcing method to GET

When I submit a form that has method="POST" the view that handles it is getting method GET, and I can't seem to get it to be a POST, which is necessary for file uploads. Short of just canning my existing (was working a week ago, before upgrade to 1.4) and trying to use the form upload the sample from https://docs.djangoproject.com/en/dev/topics/http/file-uploads/, can you see what is going wrong here? I tried a fresh session using Chrome Incognito with the same results. When I don't include method="POST" it submits with method GET and the fields are included in the request.GET dictionary in the email. However, when I change to POST/post, it remains method GET and the fields are not in the request.POST or the request.GET dictionaries. Is there a bug in Django 1.4 that is causing this behavior? Is there something I'm missing? I tried to make a simple example to rule out all extraneous potential variables.

Simple test scenario:

urls.py:

url(r'^upload_test/+$', 'views.presentation.UploadTest'),
url(r'^uploaded_test/+$', 'views.presentation.UploadedTest'),

views/presentation.py:

def Notify(subject, body):
    """
        Send an email to <to_email>, from <from_email> with the
        subject and body supplied.
    """
    send_mail(subject, body, '<from_email>', ['<to_email>'], fail_silently=False)

def UploadTest(request):
    Notify("UploadTest", "METHOD: " + str(request.method) + """

    """ + str(request))
    return render_to_response('upload.htm', context_instance=RequestContext(request))

def UploadedTest(request):
    Notify("UploadedTest", "METHOD: " + str(request.method) + """

    """ + str(request) + """

    FILES:
    """ + str(request.FILES))
    return render_to_response('upload.htm', context_instance=RequestContext(request))

upload.htm (note method is POST, I tried lowercase just in case as well):

<form
    id="upload_file_form"
    action="/uploaded_test"
    method="POST"
    enctype="multipart/form-data"
    target="_blank"
>
    {% csrf_token %}
    <input type="text" name="extra_field" value="extra post field" />
    <input type="file" name="upload_file" id="upload_file" />
    <input type="submit" name="upload" value="Submit" />
</form>

Results of simple test scenario

The emails I get (note the first is the form pre-submit, the second is the posted form page):

    FILES:
    <MultiValueDict: {}>

Doubtful, but perhaps it is something wrong in my wsgi file, or in my Apache site directive. Here are those, just in case:

...wsgi:

import os
import sys

path = '/var'
if path not in sys.path:
   sys.path.append(path)

path = '/var/www'
if path not in sys.path:
   sys.path.append(path)

path = '/var/www/site'
if path not in sys.path:
   sys.path.append(path)

os.environ['DJANGO_SETTINGS_MODULE'] = 'site.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

Apache sites-enabled directive:

    RewriteEngine on
    RewriteCond %{HTTPS} !=on
    RewriteRule ^/(.*) https://%{SERVER_NAME}/$1 [R,L]

    RewriteEngine on
    RewriteCond 1 =1
    RewriteRule ^/(.*) https://%{SERVER_NAME}

Perhaps I need to read more about the urls.py or regular expression. I accidentally changed the form to post to action="uploaded_test" without the opening slash, and received a 404 error report which has the request.method as "POST," (what the ?!@#$*&)...??? This meant that it had to be something with my posting url! I had it as:

'^uploaded_test/+$'

I changed it to:

'^uploaded_test$'

and verified the form was posting to action="/uploaded_test" and it worked! I changed urls.py to:

'^uploaded_test/$'

and changed the form to post to action="/uploaded_test/" and it also worked! I had the /+ in most of my urls entries so that I could accept either /loc or /loc/ for many entries. I think I will change them back, now. I don't know if this is a bug or something I don't understand about the regular expression /+ syntax.

Have you tried an if-else statement in your presentation layer?. for example if request.method == 'POST': and then the rest of your code.
