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. I wonder if it or ZPatterns are causing this phenomena.
I use absolute URLs for images, so that's not an issue.
Could LoginManager be denying access to the images on a refresh?

I'm experiencing the same thing with Navigator 4.08 on NT4 against Zope 2.1.6 from Debian "potato". Disabling Navigator's cache fixes
the problem.
That's not a satisfactory solution, though.

I have tried to track down a solution to this problem for a couple of days.
I have Zope 2.1.6 (binary release, python 1.5.2, win32-x86) installed.
Everything is working great, but when I use Netscape 3, 4.X , every time I hit the reload button or come back to the page at a later date all of my images won't display. It just shows the classic broken image icon that is default for Netscape.
I know that it isn't a Zope issue because the zope.org site works fine!
This is obviously not acceptable to any viewer, could someone please give me a work around or a solution to this problem.
Thank you in advance!

John, Add the following lines just before line 186 of image.py and tell us what comes out on the console (not your browser, but the console--assuming the console is visible). print header print DateTime(header) print DateTime(header).timeTime() Shane john@nurl.net wrote:

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? ------------------------------------------------------ Andres Corrada-Emmanuel Email: andres@corrada.com ------------------------------------------------------

One easy way is to visit /Control_Panel/manage_debug which shows you the details about each active connection, including your own. Another possibility is to create a DTML method called "req" in your root folder which simply calls <dtml-var REQUEST>. I solved the 1900 problem by changing DateTime.py so that years 00-69 are now translated to 2000-2069. That's the way it was supposed to work in the first place; I think something fell through the cracks awhile back. Everybody is counting on having 64-bit processors or better by the year 2038, and if we do, performing an int() cast will be a safe thing to do. Shane

Are you running Zope in single thread mode? If I recall correctly, Netscape fires off a bunch of threads to simultaneously download the images on a page. It could be that Netscape is tying up the single thread, and getting impatient with its other requests. -- Steve Alexander Software Engineer Cat-Box limited
