[Zope] Missing pictures

[William JOYE]

Hello,

I have notified that every time on my web page one picture is missing (with
IE and Netscape). When I refresh the page there is another picture missing
and the first is OK. After another refresh, the first is missing and the
second is OK. And so on...

I use Apache and Zope 2.1.6 under Linux. In the Apache log, I have notified
that http code is always 304 but when pictures are missing in web page the
transferred size is '-' and no '0'.

What's goes wrong ?
