Hmm.. have heard of this before. Think the previous person seeing such
symptoms nailed it down to the disk being full on the client computer
making IE a bit confused about what it had in the cache..

You would need to edit the code to do this it seems. Should not be very
hard, just look for HDR_IF_MODIFIED_SINCE in client_side.c.
