Not sure if this will do anything, but perhaps it will.
I created a file on several Appache servers called default.ida containing garbage and weighting about 50 megs in size.
I’ve not had a chance to test the effects on the CodeRed worm infected boxes nor the results of this, but it in theroey should choke them. I know it choked my browser, at least in netscape on a linux box and then an IE5 browser on a MS box.
Maybe a fix? Who knows.
