As we all know, Pre-fetching helps accelerating performance for dynamic content. It will be a great a help if someone can help me with following question or can refer me to a good documentation about it.
1. On which content-types, pre-fetching kicks in?
2. When pre-fetching is enabled, Do we make multiple TCP connection with origin server to fetch the content?
3. If Yes, What is the limit of the TCP connection we open with origin server for pre-fetching?
4. How do we make sure that we are not overloading origin with establishing multiple TCP connection?
