RE: [Zope-dev] Fighting with ZServer
Dieter, Yes, I have, and I spent hours tearing apart my site thinking I'd seriously screwed-up when suddenly all my images refused to load. But that was just on my Solaris 2.6 server. PCs and even Macs render my pages beautifully. It's just Netscape Communicator for Solaris that causes a problem. I don't have a clue. But, I can tell you why your logs wouldn't be showing up. Netscape caches images so that it doesn't have to keep reloading them from the server. If it's reading a cached image, you won't see an entry in the server log. Hope this helps, T.J. -----Original Message----- From: zope-dev-admin@zope.org [mailto:zope-dev-admin@zope.org]On Behalf Of Dieter Maurer Sent: Monday, August 21, 2000 2:36 PM To: zope-dev@zope.org Subject: [Zope-dev] Fighting with ZServer Since this afternoon, I am fighting with ZServer. Currently, it seems Zserver is winning .... I do not understand, what I see... At work: Zope 2.1.6, Sparc Solaris 2.7, Linux Netscape 4.51 Sometimes, images are not shown by Netscape (broken image). No "simple" reload is able to change this, however a "forced" reload lets Netscape show the image correctly. From then on, the image is always shown correctly: by "simple" reload, "forced" reload or directly (served from cache). The strange thing, inside "Image.index_html" the failing "simple" reload and the succeeding "forced" reload look completely identical. At home: Zope 2.1.6, Intel Linux 2, Linux Netscape 4.5 All images are always shown correctly. However, there is no log entry in "var/Z2.log" for about 50 % of the requests that are answered by a 304 response. It is non-deterministic whether a log entry is written or not. Did you ever see something like this?

Yup, this is 'the Netscape with Images problem' :-(

This does seem a lot like the "If-Modified-Since problem" in 2.1.6 caused by certain versions of Netscape sending crap header information back to Zope, and zope throwing an exception. IIRC, 2.2 handles this much better... Check these bugs and see if any help: http://classic.zope.org:8080/Collector/1014/view http://classic.zope.org:8080/Collector/1388/view And try it with 2.2 to see if it's still broken... cheers, Chris
