'Prevent Gateway Timeout from AWS ALB while waiting for Nodejs Express response
I have an Express Nodejs application running in a Docker container on AWS ECS. The server renders images which can sometimes take over 2 minutes. Is there a possibility that the ALB does not cut the connection after 2 minutes?
And I know instantaneous rendering could also be solved with pre-rendering or caching, but that's not the question.
Sure, I could increase the ALB's idle timeout from 120 seconds to a higher value, but I might have thought that the Express application could reply with a keep alive or similar to the ALB request meanwhile. Is something like this possible and if so how?
