IE 6 hangs after XmlHttprequest for 5 minutes

[pfefferl]

Hello,

i have a ajax-webapp (prototype.js) which works without any problems
with IE (also 6.0), FireFox, Opera etc..

Now I have a single client (W2K, IE 6.0.2800.1106, SP1) who has a
strange problem.
Every time, the client sends an async.-POST-xmlhttprequest, IE sends
the request succesfully after 5 minutes - i don't know, what IE does
during this 5 minutes.

For test you can visit https://www.schuldenonline.at/connection and
make a single request or send multiple requests.

Besides: I know there are problems when using SSL, IE 6.0 and the
parameter "keep-alive". Therefore the connection after every request
will be closed.

Can anyone help me to find out what the reason for this strange
behavior is?

Thanks
Ludwig Pfefferkorn

I solved the problem by myself.
The problem was the wininet.dll 6.0.2800.1106 from the patch
http://support.microsoft.com/kb/328970/de. The strange behavior stops
if I install the patch http://www.microsoft.com/austria/technet/bulletin/ms06-067.mspx
or I only replace the wininet.dll 6.0.2800.1106 by wininet.dll
6.0.2800.1579.
