To help the debugging I also found an url that is accessible to everyone:

Subject: [squid-users] images occasionally don't get through

Situation: user using microsoft internet explorer 8 (altough I've seen it
with other versions as well), Squid version 2.7stable3-4.1 (Debian package).
Very often when that user surfes to a site, no images (or not all of them)
are shown. When he presses ctrl+refresh, they do appear.
In the access.log I see this:

192.168.0.99 - - [12/Feb/2010:13:57:59 +0000] "GET
http://SITE/equotes_BPNL/images/new_imgs/bl-watermark.jpg HTTP/1.1" 200 621
"http://SITE /equotes_BPNL/shoppingBasketNavigation.do" "Mozilla/4.0
(compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0)" TCP_MISS:DIRECT

192.168.0.99 - - [12/Feb/2010:13:58:03 +0000] "GET
http://SITE/equotes_BPNL/images/new_imgs/bl-watermark.jpg HTTP/1.1" 200 3679
"http://SITE/equotes_BPNL/shoppingBasketNavigation.do" "Mozilla/4.0
(compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0)" TCP_MISS:DIRECT

As you see, the first time only 621 bytes are sent, after the refresh the
full image as it seems is send.
I verified that the filesystem has enough diskspace (69% space used, 23%
inodes in use).

How can I fix this?
