[Zope] 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: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Dieter Maurer Sent: Monday, August 21, 2000 2:36 PM To: [EMAIL PROTECTED] 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?

That may be possible. However, this avoids browser caching of the images (at least until 2002-3-15). I think, disabling the caching is not a good thing. Furthermore, it does not explain, why netscape displays the image as broken. It should get a nice 304 response which is usually handles correctly. By the way, Zope should cope with rounding problems for the "If-Modified-Since" headers.

[Zope] RE: [Zope-dev] Fighting with ZServer
To your image in properites add a string property called Last-Modified with value Wed, 15 Mar 2002 19:02:17 GMT And your broken image problem will disappear. This is not zope specific, I think it's apache since I've had the problem with PHP4 using a fusebox architecture. -Kevin Smith >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.
