Come to think of it... Under what circumstances do we most often find people looking for nonexistent files in our webspace?
#1 They're trying to poke holes in php files belonging to people who have rashly left everything with its default name.
#2 They're looking for evidence of prior visits by malignant robots who left behind something with a characteristic name.
Yes, OK, sometimes the browser asks for that Cross-Platform Thingummy which is apparently legit, but on the whole, on balance, most of the time...
