7233	placing request.POST.copy() in session wipes all session values	mikechambers	nobody	"Version : (0, 97, 'pre')

The issue is that it appears trying to store a QueryDict (request.POST, or a copy of a QueryDict) in the session, will wipe all session data.

You can see the original thread here:

http://groups.google.com/group/django-users/browse_thread/thread/260d9b94f773655e

Basically:
{{{
request.session['form_post_data'] = request.POST.copy()
request.session['foo'] = ""bar""
}}}
Then, in another request:
{{{
print request.session.keys()
}}}

prints []

(i.e. no keys)

But:
{{{
request.session['foo'] = ""bar""
}}}
then in another request:
{{{
print request.session.keys()
prints ['foo']
}}}
There seems to be two potential issues:

 1. Cannot store request.POST.copy() or request.POST in the session (should you be able to do this?)
 2. Trying to place request.POST.copy() in the session wipes all session values.
