Django中间件的正确排序是什么？

这个页面:https://docs.djangoproject.com/en/1.7/ref/middleware/#middleware-ordering有/暗示以下排序(问题1:我是否正确假设列表的顺序正确？)

UpdateCacheMiddleware

GZipMiddlewaree

ConditionalGetMiddleware

SessionMiddleware

LocaleMiddleware

CommonMiddleware

CsrfViewMiddleware

AuthenticationMiddleware

MessageMiddleware

FetchFromCacheMiddleware

FlatpageFallbackMiddleware

RedirectFallbackMiddleware

虽然https://docs.djangoproject.com/en/dev/topics/http/middleware/#hooks-and-application-order上的图形似乎表明CommonMiddleware应该在SessionMiddleware之前:

在Django 1.5 django-admin.py startproject生成(https://docs.djangoproject.com/en/1.5/topics/http/middleware/#hooks-and-application-order)

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
)

而以1.6开头的版本生成(https://docs.djangoproject.com/en/1.6/topics/http/middleware/#hooks-and-application-order)

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
)

问题2:我应该更改1.5项目中的顺序,以便SessionMiddleware在CommonMiddleware之前吗？

问题3:切换订单时如何处理不同的请求？
