iRule to route traffic to different pool when pool members down in default pool

nitass, thank you for all the help here. I do have a ticket open with F5 in regards to this issue and one of the recommendations my support engineer gave me was to post my problem to this forum.

 

 

I have been able to work around the issue I was having by doing the following:

 

 

setup iptables on the web servers to nat the destination to the web server on port 80

 

 

setup apache with mod_rewrite to rewrite anything that is not destined for my web server to the web servers fqdn/uri

 

 

removed the http_profile, tcp_profile from the wildcard virtual server.

 

 

changed the irule so it does not whitelist based on hostname in the http request during an HTTP_REQUEST but to whitelist based on destination IP address during CLIENT_ACCEPTED. removed the fqdn/uri rewriting from the irule.

 

 

This works in our environment but would be much more flexible if it could be handled in the load balancer and use hostnames instead of IP's. However this is satisfactory for us at the current time.

 

 

Thanks again for all the help!!!

 

 

Best Regards,
