Thanks for the report.  This bug was fixed last week but it doesn't look
like it made all the way out to california.  Brian is fixing it as I
type.

The problem is with Apache and Last-Modified HTTP headers.  It's a
little detailed, but basicly we added some code to take advantage of
caching, and Apache beat us with a stick because of it.  The net result
is that Apache thinks it should return a 'Not Modified', when the script
wants to return a 200 (Success) and some data.  So Apache does a strange
thing.  It logs a Not Modifed, returns a 200, and ignores the data.  ??

Title: IE5 /Manage waiting/incomplete page 1.11.0p1

Expected Fixed in 2.0.0 and Response was:
"This turns out to be a side effect of a bug in the
Last-Modified / If-Modified-Since header handling
for Image (and ImageFile) objects which has recently
been fixed."  -- Brian Lloyd brian@digicool.com


My route to DigiCool seems quick as shown in
this trace below.  I suspect some config error in
at the server....

This is not a problem at the ZOPE site.
What version of ZOPE is used at the DigiCool
site?
