Microsoft proxy server keepalive

[wrsteve]

We are balancing 5 microsoft proxy servers. The keepalive we are using is a TCP 8080. We have seen occasions where the proxy will respond to an 8080 syn packet but the proxy service is down. Is there a better keepalive to use for load balancing a ms proxy server?

tcp is fine.

Also to go down you need to miss 3 retries in a row by default. So it makes even more suspect.

We should investigate why it was reported down even if the proxy responded.

What type of CSS ?

What software version ?

What keepalive frequency ?

What keepalive retries ?

How often do you see the problem ?

Does the service come back up immediately after ?

Sniffer trace available ?

Thanks,

Gilles.
