This question is quite general as I want to understand the (security) benefits of a ‘timeout’ in general.
For our Nginx proxy-server, we have been using HTTP/S timeouts where we came across the issue were the Nginx server returned a time-out. Now, we have solved this by simply increasing the Nginx time-out. We keep upscaling the timeout, may it be for a specific endpoint, it seems we keep pushing an underlying problem. We see this problem again and again where I asked the question: Why do we even want to have timeouts?
Thinking about some malicious attempts, like sending a bulk of load to the server, if Nginx gives a timeout (or any ‘timeout manager’) the server would still be processing the data.
So, why would we use server timeouts and what would be a better way to solve the issues for reaching the timeout cap every time? Would be paradigm like WebSocket, SSE or (Long-)Polling resolve this?
