Hi Bob,

You need square braces around the HTTP::header command: 

when HTTP_REQUEST {
   log local0. "[IP::client_addr]:[TCP::client_port]: User-Agent: [string tolower [HTTP::header "User-Agent"]] requested [HTTP::host][HTTP::uri]"
   if { [string tolower [HTTP::header "User-Agent"]] contains "github.com/tenderlove/mechanize"} {
      log local0. "[IP::client_addr]:[TCP::client_port]: Rejected request"
      reject
   }
}
