[Zope] temporary document

[Jerome Alet]

Hi there,

I'd want to be able to create a file object (PDF) in the ZODB, which 
would be downloadable during say one hour or half an hour, and then 
which would disappear automatically. 

Is it possible ? If yes then how ?

I've tried to create it in the temporary folder at ZODB's root, but
it doesn't disappear (maybe I've done something wrong)

I've searched the archives on zope.nipltd.com but without finding
what I want.

thanks in advance.
