I am having a problem with a CSS11501, everything is working fine performing simple load balancing accross a number of IIS web servers.
However, I need the http keepalive to poll a file on the each server, but the IIS configuration requires that I use a hostheader.
I have tried using redirect-string and using a name instead of an IP address but the CSS just resolves the name and puts the ip in the config.
An pointers would be gratefully received.
My advise is to use script ap-kal-httptag, where the value of this header(tag) can be specified as the last argument.
Considering this example configuration
ip address 10.10.10.1
keepalive type http
keepalive method get
keepalive uri /test.html"
Modified one can be
ip address 10.183.121.241
keepalive type script ap-kal-httptag "10.183.121.241 /test.html www.test.com"
Replace string www.test.com with the content of host header your server expects to see
instead of IP address. You find it in the IIS configuration, near the place where you
configure it to listen to host names only.
Hope it helps!!
