The same paradigm holds true when designing the infrastructure or the way clients can access data. If you're familiar with the paradigms behind many design and programming approached, such as OOP, you will probably recognize the importance behind " separation of concerns". The best way to mitigate this issue, as well as a number of other issues, is to place a proxy layer such as nginx or a firewall between the node.js application and the internet. I cannot write these real programmer languages.īut all of us are helped, if somebody pushes this on Github.īecause the community there once deleted my thread about mitigating Slowloris. I think this want to be solved on C or C++ base. What can the world do to get rid of this scourge? So this is - not - feasible in sense of high available server. It is possible to transfer requests and responses from net to HTTP-Server and back.īut this takes 2 sockets for 1 incoming message. The problem I can see is, both services have to listen on the same Socket on Port 80 and 443. The idea to `destroy` the `connection` in case of `Slowloris` is this.

I came to the question, if I can combine net and a HTTP Server for mitigating Slowloris.

HTTP Header or POST Data characters get transmitted slowly to block the socket. The fix - new defaults and probably new API - will be there in 1 or 2 weeks. I managed to convince the Node.js core team about setting a CVE for that.
