    I have been able to reduce the effect of the Nimda worm by implementing Host
    Headers. Now every nimda originated request gets a 404, before some were
    sent a 404, but also some error 500.
    
    This works because the worm scans base on IP only.
    
    Its not much of a help but the logs are now under control. Scans are about
    10 times that of CodeRed.C so far.
