Badly - but I think what he was looking for was.... Breaking down and analysing the question well. It is a large and broad question so focusing on a smaller area that is more relevant for me would make sense. We eventually got to the "http request response cycle" and broke down the technologies there. I knew my stuff but it took a few moments for it to come back into current memory as I simply do not use it every day. I believe he would have been more impressed if I could have directed the answer a bit quicker, had the knowledge recall quicker and answer with confidence.
