IE intermittent problem

[Velvet]

I'm having an intermittent problem with IE
6.0.2900.2180.xpsp_sp2_gdr.050301-1519 installed on Windows XP.

The images, style sheets and JavaScript files are not loading to the
browser. Sometimes a refresh will fix the page, sometimes I have to delete
the cache before it will load properly again, sometimes that doesn't help
either. This only seems to happen with IE. Netscape and FireFox seem fine.
I have only been testing this on one system so I don't know if it's an XP
related problem.

The Server is running IIS 5.0, with .Net frameworks 1.1 and 2.0. We are not
using 2.0 yet.

I have asked the host about the problem and they say that they know about it
and that it's an IE problem. However I cannot find any information in the
KB articles about it. The server is recording a 304 error on the images,
*.css and *.js script files, according to the log files. the tech at the
host company tells me that the server is under a normal load, and this
problem was happening late Tuesday night when hardly anyone was on the
server when I was updating one of our ASP.NET 1.1 applications, so I believe
it.

I found this article, which is close but it states a 302 error code.

If anyone has any more information about this bug, I would be grateful. I
don't think that the

Hi Velvet,

Thank you for your post.

Http status code 304 means "Not Modified", which I think is ok for the
server.

I suggest following steps to pin down this problem:

1) Create a simple webform which use one image, one stylesheet and one
javascript file, verify if this works or not. If it works, the problem may
related to specific webform and resource files.

2) Set IE's cache size to zero, and see if it works.

3) Use File Monitor from http://www.sysinternals.com to monitor IE process,
to see why it failed to read cached resource files.

4) Test on more client system to see if this problem is specific to one
machine or one os or one IE version.

I'm looking forward to your findings.

Since posting this problem, I downloaded the IIS logs and went through them.
It looks like the page is getting the 302 error and the content
files are getting the 304 when IE fails to load the content. When the page
and content are successful, both page and content files record 200 which is
a successful request.

Also, I thought that this was related to ASP.NET, but according to the logs,
it's happening to our *.asp and *.htm pages as well as the aspx pages. I
can see in the log that a person didn't get all of the content from the page
(302) and then the pages was refreshed by that same person and the next time
and it was successful (200). I also discovered that I'm not the only one
who is getting this error. The logs show this happening to IE6.0 and I.E..0
users.

IE started doing this about two-three weeks after I added our forums
application to our server. I can't pin down the exact date it started
because my host only keeps one months worth of logs, but I'm thinking that
it began somewhere near the end of April. I've asked the Host if they have
the logs for that month, but I doubt that they would have kept them.

In any case, since MS has put out a KB article about this, I will hope that
htey fix the problem soon.

Thanks!
Velvet
