Thanks Bjorn, now I remember the last-modified issue.
As I remember it, someone said that the line is commented out for a reason
not known... that's why I didn't change it :)

> PROBLEM
> Apache (1.3.28 and 2.0.47) will not cache content with just an Expires
> header, but it will correctly cache content with a 
> Last-Modified header.
> This problem has been reported before in 1999 by James Cooper, but the
> bug request seems to have been forgotten/ left behind.
> 
> It makes sense for dynamic content to produce Expires headers, not
> Last-Modified headers, so this is a problem.
> 
> Looking at the code for Zope, it seems that the standard HTTP
> accelerator product used to produce a Last-Modified header, but no
> longer does so, thus making it useless with the current versions of
> Apache.

> The problem has been re-reported to the Apache group with patches:
> http://nagoya.apache.org/bugzilla/show_bug.cgi?id=23129 (for Apache
> 1.3.28)
> http://nagoya.apache.org/bugzilla/show_bug.cgi?id=23130 (for Apache
> 2.0.47)
> 
> 
> WORK-AROUNDS
> 1) Produce a Last-Modified header yourself by using
> 2) Patch Zope's standard HTTP accelerator product so that it 
> produces a
> Last-Modified header (the line is commented out now)
> 
> SOLUTIONS
> 3) Patch Apache (see bug report links above for patches)
> 4) Wait until the problem is hopefully fixed in Apache
