PROBLEM
Apache (1.3.28 and 2.0.47) will not cache content with just an Expires
header, ...
This is required by the HTTP 1.1 specification...

I know, I was just trying to figure out how this was supposed to work.
Currently setting Last-Modified seems to be the only way to get
something cached in Apache; Expires alone is no good, and adding an Etag
header doesn't seem to have

Also, in most cases, the content of pages doesn't all come from one
object, so Last-Modfied doesn't really make sense since it should refer
to the whole page. I think the problem is with Apache's inability to
cache content with Expires

You can google on the phrase to get a ton of more-or-less abstract overviews
of the concept. The short course in ZODB is that, when MVCC is in effect, a
read will return the state of the object as of the time the current
transaction began,
Upgrading a product whose permissions have been renamed can be a pain..
you lose your permissions settings and have to recreate them.
Has anyone seen a script that would walk the zodb and replicate the old
permission settings under the new name ?
