HTTP MONITORING with IIS restriction
Hi,
Our IIS servers are configured such as no http requests based on ip address are accepted from the clients, hence, the LTM monitor always gets a 503 service unavailable when sending GET health check.
any idea or workaround for this?
thanks.

- OMNimbostratuswell, the keepalive URI in the server is a script that checks other services and returns an HTTP 200 OK if it succeeds, therefore, I have no other choice than expecting the 200 OK string as a receive response.
- Minn_62043CirrostratusDo you mean if the client ip is not unresolvable, IIS will return 503? If it is the case, you can try to add LTM IP's into IIS system's host file.
- hooleylistCirrostratusGood thought Moo. Another possibility is that the server sends a 503 if there is an IP in the host header value. But that should be solved by hardcoding a valid hostname in the monitor's send string.
