I think we need another clue. How about a URL to the problem 
page?

[css-d] [tech] cached images not displaying

2006-05-17 Thread Phil Glatz
This is a problem I've been wrestling with on and on for the last few 
months.  It has been extremely difficult to get a handle on, since it 
is intermittent and often difficult to reproduce.

I am bringing it to this list because it may be a CSS problem; it 
could also be an IE quirk, and am hoping somebody else may have 
experienced this problem..

The HTML validates perfectly, and the CSS is conservative level 2 and 
correct, as far as I can tell.

The issue: I'm testing on XP Home, using Firefox 1.5 and IE 6.  No 
problems with Firefox.  With IE, a series of 60x60 gif images are 
inconsistently being displayed.  Sometimes they show, most often when 
I flush the browser cache or start up clean.  But usually I just get 
a small empty box where they should be.  I have a light border around 
each one, so I can see where they are supposed to be.

I tried saving as "web page complete", and this version always shows 
all the images, leading me to suspect something about the way the 
pages are being served.  This is on a shared server at dreamhost, 
using: Apache/1.3.33 (Unix) mod_throttle/3.1.2 DAV/1.0.3 
mod_fastcgi/2.4.2 mod_gzip/1.3.26.1a PHP/4.4.2 mod_ssl/2.8.22 
OpenSSL/0.9.7e, with Zend memory manager.

But since the problem never occurs with Firefox, I haven't been 
thinking too hard that the server is at fault.

Here is one thing I noticed - I specified width and height attributes 
for the images.  If I right click on an image (or where it should be) 
and look at its properties, I see the correct width/height 
images.  But the "size", created", and "modified" fields all show 
"not available".  With the version I saved on my computer on local 
disk, which always displays correctly, has the correct values filled 
in for these fields.

If I view the access log as I reload the page after clearing the 
cache, I see the image requests, with a status code of 200, and a 
correct size of 480 bytes.

I don't know why the size/created/modified values aren't available 
when I look at the image properties, but think this may be a valuable 
clue.  Can anyone shine light on what this means, and why it is happening?
