Nope.
The only solution seems to be to tell rabbit to not cache anything.
Just compress images and text.

It then returns - instead of 0 byte figures in the http response.

Could this be something that could be changed in the future or to
correct this problem?
When Explorer verifies the cache it gets a "-" instead of "0" if the
cache is good.

I am wondering if one fine option may be to have a squid proxy be the 
"first hit".
Squid then gets the page from Rabitt ignoring Explorers ability to 
examine its own cache (is that the problem?).

I do not know if Squid and Explorer have a better relationship but I 
will try it.
