Lucy is correct. They just took the day off. They are back today. Just two IPs and two URLs, which I blocked in htaccess. From what I have been able to determine, they appear to be probes checking to see if the server my site is hosted on can be used as a proxy. I would block them anyway. Most of them are from China and Russia, Poland, etc. Today's IPs were:
61.160.195.nnn
222.186.128.nn
