Hello Hiranmayi,

Having them would be very interesting of course.

It is not so clear how far you can get. I usually declare that ModSec is no
good fighting standard DoS attacks. As for websockets, you may face a problem
where ModSecurity does not give you proper access to the traffic in question.

Checking standard HTTP headers should not be a proble, though and writing a
few rules for the websocket use case seems feasible.
