The DropRequestList looks like this now in the interchange-handler
DropRequestList /default.ida /x.ida /cmd.exe /root.exe /xmlrpc.php
Since I implemented this, the site has been hit by the worm 6 times, but
my script has not detected the site going down.
I still think there is a problem somewhere, either in apache,
mod_interchange or interchange, however I'm not sure how to go about
finding the issue without an easy to reproduce case.
Once someone can come up with a reproducible case I will look into a fix
