IE hangs with drawmap.php

I would not use IE either, but some clients do:-(

In the meantime I can give some more infos on the problem:
I can reproduce the crash when I load the same URL twice:
- copy a valid URL to drawmap.php directly to the address bar of IE
>> image loads
- press F5 to reload the same URL
>> IE hangs

So normally in a chameleon app every URL should be unique (that is what 
the dummy var is for). However I suppose IE does something nobody knows 
about, e.g. call the URL more than once.

The output format of the map seems not to be the cause of all that, as I 
guessed before.

I have built a small test application to reproduce the bug:
http://ex1.ruf.uni-freiburg.de/crashie/obsrv.php

I will also have to check if maybe apache blocks repeated calls?
