Using the %{If-Modified-Since}i directive in the Apache log, we have been
able to confirm that Netscape 3.01 and 4.06 on Win32 are sending
If-Modified-Since with "16-May-00" type dates. Dieter's solution indeed
fixes the problem by removing the Overflow error that they cause when the
int() function is called on them.
I noticed that Zope 2.1.4 does not have these int() calls in the offending
section of lib/python/OFS/Image.py but they are present in 2.1.6. Why were
they introduced on the latter version? Can they be removed in future
versions?
No, they can't - HTTP datetime headers specify time in whole seconds, while
the time() function on Unix machines returns time with a floating point
time. In order for Zope to work correctly the you have to make timeTime()'s
result be a whole number. long() would be fine though, or floor().

I have stepped through the debugger with the call of
ZPublisher.Zope('/path/to/image', d=1). Upon immediate entry into the
ZPublisher/Test.py module I can set environ['IF_MODIFIED_SINCE'] to
something reasonable such as 'Wednesday, March 15, 2000 19:02:17 GMT' and I
get no error as I step through the code. This exonerates the Zope python code.
The question then remains who is producing the buggy If-Modified-Since that
puts the date back to 1900. Does someone know how to trap the headers that
are sent to Zope so they can be inspected?

That explains the exception:
1900 is a bit too far in the past.
Seems that Netscape sends such a strange "If-Modified-Since" header.
You can try to fix this problem, by removing the "int(...)"
in "OFS.Image.py:186"
mod_since=int(DateTime(header).timeTime())
mod_since=DateTime(header).timeTime()

You Rock Dieter,
Thanks to everyone for their input!
This has solved the nasty Netscape Image problem for now!

RE: [Zope] Netscape Image Problems (LoginManager?)
Well I have determined that it has nothing to do with PTK or Login Manager, well I think anyway... If you hit reload it breaks the images on the root level, if you put your cursor in the Location, or URL field and hit enter it reloads fine. I truly don't understand this problem and it only does it with images, in Netscape, is this an issue that everyone is just accepting or is there a fix for it. j At 08:51 AM 5/22/00 -0500, you wrote: I'm not using PTK, but I am using LoginManager.
