Description

alert http any any -> any any (msg:"CURL1"; flow:established,to_server; content:"GET"; http_method;  content:"curl"; http_user_agent; threshold: type limit, track by_src, count 1 , seconds 60; sid:1;)
alert http any any -> any any (msg:"CURL2"; flow:established,to_server; content:"GET"; http_method;  content:"curl"; http_user_agent; threshold: type limit, track by_src, count 1 , seconds 60; threshold: type limit, track by_src, count 1 , seconds 60; sid:2;)

The first rule will trigger an alert, but the second one will not trigger an alert. The second one is faulty and contains two threshold fields. Rules that contains error is often listed in suricata.log and not loaded. It would be good if similar validation is performed on these cases.
