Hi Guys,

Just a quick question: how could I go about blocking a HTTP request based on its string?

Let's say I wanted to block the following request:
190.20.173.246 - - [07/Sep/2011:15:28:17 -0700] "GET /?=()()()!2000 HTTP/1.1" 200 13555 "-" "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US)"

Thanks in advanced.

if ($args ~ =\(\)\(\)\(\)) {
return 403;
}
