Welcome to WebmasterWorld Guest from 22.214.171.124
Just generated several 404s within too short a time frame for a human.
It basically took the file/directory names from one site but the domain name from a different virtualHost. Neither site is the default virtualHost or real IP address, so it's not that it doesn't understand HTTP1.1. I suspect it's having issues with server-side redirection.
I'm going to ban it unless someone can point to it having a legitimate status.
It's an educational site, so will attract some traffic from the far east.
In any case, there are 22 sites on the server and I try to use a global anti-spam config, which wouldn't be possible if I went along the IP-banning route.
