Default HTTP monitor v10.2

1. What is the health monitor doing when you leave the send string empty ? Is this simply a socket based check ? Which would give us not much more than a standard TCP monitor?   ...

If there is no SEND string then the default monitor will just send a 'GET /' . The server is marked up if ANY content is received (it will not check the details of that content).

 

Notice this must be HTTP content. It is possible to receive just an HTTP Header response, but no actual content (Header: content-length: 0) and this will result in the monitor marking the pool/node as down.
