Hi Hum,
I'l give it a go, but to add to the confusion, the orginal internal health monitor I had which was NOT working has now started to work on the standby unit. There aren't any issues having monitors querying the same pool members is there? It almost seems to be when one monitor works the other fails.
The internal monitor was just doing a
GET /exam-services/student HTTP/1.1\r\nHost: \r\nConnection:Close\r\n
and expecting HTTP/1.1 200 OK
Although this is a HTTPS monitor it was suggested I didn't need to specify a client certificate or client key because the monitors don't use them.
Regards,
Craig
