IE 8 Parsing issues?

Hello,

since a few month we're having strange requests in our web server logs.
Example:

2010-01-27 18:00:35 W3SVC183691552 194.183.128.104 GET
/SysRes/GLOBALSkin/Ski/head><body+onload= - 80 - 194.183.153.12
Mozilla/4.0+(compatible;+MSIE+8.0;+Windows+NT+5.1;+Trident/4.0)
http://my.domain.at/ 200 0 3 21699 757 46

Sometimes embedded resources like Scripts or CSS files are not loaded
correctly. The path to the external resources is broken by adding any HTML
code snippet of the page which embeds the resources. It happens on different
pages / applications on our servers. The only similarity in these log
entries is the User agent (IE 8). We cannot say that it's happening on all
IE 8 clients, there are not too much broken requests.

Any hints? Does anybody have the same problems?

Best Regards,
Andreas

Proxies... SQUID. It seems to have fixed itself in the wild. Are your
machines fully patched? Visual Studio and .net CRL fully updated?

IE 8 Parsing issues

We observe the same problem.

IE8 browsers loading pages from our server sometimes make requests to in-page resource files (.js, .css etc) with damaged filenames.

We have been able to verify that often 4096 bytes are dropped in the source code, ie. if in the html source it said
<script type="text/javascript" src="/h/menu.js"></script>
the request on our server my look like
/h/menSOMETHING
where SOMETHING is a html fragment from the same page, further down by 4096 bytes. We have also seen case where the distance is different from 4096 bytes.

It seems that some code triggers a bug in IE 8.8 which destroys the internal representation of the list of required resources for that page.

The cause does not have to be in the loaded page itself. We have traced the issue for several days, and found that it is possible that a previously loaded page damages the internal state of IE8, so that it produces the symptoms on a page it gets later.

The case is rare, we have a few hundred bad requests per day in the apache server log, while we serve about half a million pages to IE8 client browsers. IE8 makes about 25% of the user agents we see.
