Hello List I am new with ZOPE and I have installed Zope 2.5.0b3 and run some tests with sessions. Everything works fine so far. Now I want to create a SiteRoot and that means (please tell me if I am wrong) that I need an own tmp_folder with a Transient Object Container in the SiteRoot directory. I have created a tmp_folder and added a Transient Object Container with the ID session_data. A Session Data Manager and a Browser ID Manager are also in the SiteRoot directory. Every time when I restart ZOPE the Transient Object Container gets lost. If I read the help I see, thats this is normal because all Objects in a tmp_folder will be deleted when restarting ZOPE. But the original tmp_folder in the RootFolder of ZOPE always has a Transient Object Container called session_data after starting ZOPE. I guess, that this Transient Object Container is created during startup. Is there any help or a howto on how I can create my own Transient Object Container during startup. Thanks in Advance Markus
