thanks for the response Aaron,
1. Do you see the HTTPS web service logging anything for the requests? - Did not see this but from F5 using tcpdump i can see response coming on port 443 from both the DIPs
2.The monitor status for https for the 2 DIPs shows as Inactive, Down. - Is it necessary that DIPs gateway should be F5 for monitor to work?
If the gwy is upstream router, will the monitor fail?
3.There is no receive string configured on the monitor? - Is the receive string mandatory to be defined?
4. Can you use " openssl s_client -connect 1.1.1.1:443" - you mean execute this cmd from the F5 prompt ?
and for sending request, are you suggesting i use only, " GET /HeartBeat/Heartbeat.htm" and NOT the part "HTTP/1.0\r\n\r\n" ?
Plz confirm.
