在 GAE 上订购 Django-nonrel 的中间件类

Question

谁能澄清如何订购下面的中间件类？

'mediagenerator.middleware.MediaMiddleware', 
'autoload.middleware.AutoloadMiddleware', 
'django.middleware.cache.UpdateCacheMiddleware', 
    . 
    . 
    . 
'django.middleware.cache.FetchFromCacheMiddleware',
'google.appengine.ext.appstats.recording.AppStatsDjangoMiddleware', 

在文档中，顶层组中的每个中间件都被告知要排在第一位， 底部组中的两个中间件被告知要放在最后。 这很令人困惑。 以下是我正在使用的中间件的完整列表：

'mediagenerator.middleware.MediaMiddleware', 
'autoload.middleware.AutoloadMiddleware', 
'django.middleware.cache.UpdateCacheMiddleware', 
'django.middleware.common.CommonMiddleware', 
'django.contrib.sessions.middleware.SessionMiddleware', 
'django.contrib.auth.middleware.AuthenticationMiddleware', 
'django.contrib.csrf.middleware.CsrfViewMiddleware', 
'django.middleware.csrf.CsrfResponseMiddleware', 
'django.middleware.cache.FetchFromCacheMiddleware', 
'google.appengine.ext.appstats.recording.AppStatsDjangoMiddleware',

任何帮助和解释将不胜感激。

请检查一切是否正常：

'autoload.middleware.AutoloadMiddleware',   # This is loading other modules, so it goes first because we want everything set before processing.
'mediagenerator.middleware.MediaMiddleware',   # Serves/caches static files with urls starting with DEV_MEDIA_URL 
'django.middleware.cache.UpdateCacheMiddleware',   # Must be before other middleware that changes the header, so it seems that the right place for this is here
'google.appengine.ext.appstats.recording.AppStatsDjangoMiddleware', # Must be 'first' too. It collects stats of all middlewares below this. If you want stats from the middlewares above move it to the top

'django.middleware.common.CommonMiddleware', 
'django.contrib.sessions.middleware.SessionMiddleware', 
'django.contrib.auth.middleware.AuthenticationMiddleware', 
'django.contrib.csrf.middleware.CsrfViewMiddleware', 
'django.middleware.csrf.CsrfResponseMiddleware', 
'django.middleware.cache.FetchFromCacheMiddleware',
