CSS - Load balancing to Microsoft 2008 Sharepoint Application

[astanislaus]

We are tring to load balance using the CSS 11503 to two Servers running Microsoft Sharepoint 2008. Everything is working fine as far as load balancing is cocerned. But what we want is if the Microsoft Sharepoint 2008 Application is down one one server then we do not want any request for this application to be sent to this server. What sort of keepalive should we be using, because TCP port 80 is still up and responds when the Microsoft Sharepoint 2008 Application is down on this server.

I do not know much about how Microsoft Sharepoint 2008 Application interfaces / interacts with IIS and port 80, etc.

Any suggestions?

Partial Config:

===============

service FRED30

ip address x.x.x..100

protocol tcp

port 80

redundant-index 3

keepalive port 80

keepalive type http

active

service FRED31

ip address x.x.x.101

protocol tcp

port 80

redundant-index 4

keepalive port 80

keepalive type http

active

When we do the above where we have

"keepalive type http"

and then do a show keepalive we get the State as DOWN - why? But if we take out the keepalive type http command from the above services then we don't see the state as DOWN.

But even when it says DOWN we can still connect to port 80 without problem.
