hi,
AFAIK this is a known IE 5 bug, not specific to DynAPI2, or your server,
where IE always checks the server for
images unless some option is changed in the internet options. So you can
remedy it if you know what to do, but
an ordinary user wil still face the same behaviour.

> ========= Here is the details of the bug ========

> 1. This only happens in MSIE browsers. Netscape browsers DO NOT exhibit

> keeps a connection to the server and tries to reload an image being
dragged
> (per IlMaestro's reply).
>
> 2. The image (you can see on the browser's status bar saying "Downloading
> ... http://servername/directoryname/n" is always called "n" wherever
> directory the HTML file creating the IbsSroll is located. My current
> workaround is to actually put a 0 byte file called "n" in the directory so
> that Weblogic doesn't complain that it cannot find "n".
>
> 3. Every time I start to scroll/drag on the scroll bar, MSIE goes back to
> Weblogic via some socket(?) that causes Weblogic to bomb out. For those
> interested, here is the error:
> <ListenThread> Problem accepting connection
> java.net.SocketException: Connection reset by peer: JVM_recv in socket
input

> 4. Error #2 happens both when the page loads first (2 times it tries to
> find "n") and when you drag the "knob" of the scrollbar. On the
front-end,
> everything seems cool (the "Downloading ..." on the status bar is annoying
> but not a show-stopper).

> 5. Error #2 is not really a big deal since it doesn't cause any major

more

"weblogic.httpd.http.keepAliveSecs=60").
