CSS 11150 - "Keepalive type http" doesn't work.

I've two webservers, A and B, sharing the same webdata on a NetApp filer. A CSS 11150 (5.033) have a content rule, C, with a VIP registred in internet DNS.

I've added A and B to C. When using default "Keep alive type (ICMP)" on services the site is fully functional. When I disable the site on webserver A, clients attached to this server get errors and are not redirected to the B webserver. This is because the CSS doesn't check the for "Keepalive type http".

The CSS thinks that A is online because it is answering for ping. This solution is not good so I tried to change the "Keepalive type" to http. This is better when something is wrong with one of the load-balanced webservers, but when activating "Keepalive type http" the CSS marks A and B down and site is offline.

Is something wrong with my configuration???

Re: CSS 11150 - "Keepalive type http" doesn't work.

By default the CSS will attempt to read http:///index.html

It looks like that may not exist. Try to access the index page yourself from each of the services.
