[Zope] Amazing Disappearing Self

[Spicklemire, Jerry]

Hi Zope Fans,

Has anyone seen a case where acquisition works, but only 
in the topmost folder? The site I'm working on shows no 
problem on a test server, but upon moving to a 
production server any URL pointing to a subfolder, or a 
document contained in a subfolder returns an error 
(below).

The production server is Red Hat linux, Zope 2.1.6

A Proxy (running on a separate server) re-directs URLS 
to the top folder of the Zope tree, just below "root". 
The oddest part is that elements available in the "root" 
(standard_html_header, and other elements called within) 
show up on the same "page" as the error message. 

It's as if Zope is working partially, but after displaying 
all the elements at the top of the tree, the silly 
document can't find itself . . .

BTW, the raw URL (as seen in REQUEST) contains lot's of 
cookie garbage which may be causing the problem. I have 
added something like 

	<base href="&dtml-relative_path;">

as suggested in some "How-Tos" at Zope.org. This got me to 
the point of having the top folder render correctly, which 
was better than I had seen up to that point. Alas, that's 
where progress stopped altogether.

On the test server everything "just worked", the way you 
sort of get used to with Zope . . .

The worst part is that some of the errors I'm seeing spill 
the guts of the cookie all over the browser screen.

BTW, what does it take to get standard_error_message to 
actually do what the dtml implies, to substitute the 
contents of an error_message object, where it exists?

Thanks,
Jerry S.
