[Chameleon] IE hangs with drawmap.php

I can avoid the problem if I force IE to use HTTP/1.0 instead of 
HTTP/1.1. But this is not a solution to ask the user to change browser 
settings....

So far in Apache I have found no configuration options that had any 
effect. But I have not yet checked everything.

The URL will be unique for the map as it is generated each time it
changes. Now if it does
not change, then it will used a cached version of it. IE is well
known to have had issue with
caching in the past, but this sounds pretty bad. Can you change your
settings to reload the
page every time and ignore the cache in IE?

Apache should have nothing to do with the problem unless you have
some special modules
turned on. Apache will just send the map when requested. Do you have
any proxy or cache
modules active in Apache? Can you turn them off and try it again?

Hi Uli,

The only trouble I have seen with IE was to do with sessions and  using 
IFRAME's.
The two don't mix very well and you have to be extra careful in this 
situation. Otherwise
I can't help you as I don't use IE! (or MS Windows) :)
