hi,
when using the django admin interface,
the logout does not work in opera.
after some investigation, i found the problem (and also the solution).
it seems that opera caches the pages quite aggressively..
by default, django-admin does not send any cache-headers.
so opera caches every page. also the logout page, so when one clicks on
the logout link, it's simply not submitted.
the easiest solution i found is to add the cache middleware and set the
cache-timeout to zero.
my config:
MIDDLEWARE_CLASSES = (
"django.middleware.cache.CacheMiddleware",
"django.middleware.common.CommonMiddleware",
"django.middleware.sessions.SessionMiddleware",
"django.middleware.doc.XViewMiddleware",
)
CACHE_MIDDLEWARE_SECONDS=0
this causes that the pages are sent with the following header:
Cache-Control: max-age=0
and with this,opera is not caching the pages anymore.
i don't know what's the correct behavior from the http point of view (if
a page does not specify any cache-setting, should it be cached or not),
but this definitively helps with opera.
p.s: please note that my configuration caches the whole site. if you
also have a non-admin part, you probably do not want to forbid caching
for that part. read the docs, there you can find info about how to
specify the cache-settings more precisely.
