I'm having lots of the following HTTP requests in my Apache access log:
126.96.36.199 - - [17/May/2012:16:33:22 +0400] "\x80z\x01\x03\x01" 200 65900 "-" "-"
My site stops working because of them. So, I just block all such IPs with my csf firewall. I am on CentOS 5.8 with Apache 2.2.4.
Can you help me understand what these requests are? I am not able to google anything and just need a point from which to start in order to resolve this issue.
