too bad the problem is the lack of 'cache-control: no-cache' and/or
'Pragma: no-cache' which force an end to end reload even in the case
of non-stale cache data.. that's what msie doesn't send when connected to
an origin server.. I don't believe that situation is different in msie
5, though I can't confirm at the moment.. but it is definitely the
issue: not IMS.

the rationale of why when traffic is hijacked that was destined to
another address that you expect the application level protocol to
optimize for the hijacker instead of the address the packets are labeled
for has always escaped me.
