Nimbostratusredirect external URL based on Pool member health
I am trying to create a iRule that will first check the health of a pool and then redirect the request to an external host based on pool availability. I have a need not to proxy the request, so I can't redirect to a LTM VIP or pool. I am trying to redirect to an external host. But I still need the utilize the LTM to base the decision of which URL to redirect to based on pool member availability.
Example:
user enters www.abc.com
iRule determines:
Pool A available then redirect to www.123.com
Pool A not available then redirect to www.456.com
Any help would be greatly appreciated!

you can do that:
when HTTP_REQUEST {
if {[active_members poolA] > 0} {
HTTP::redirect www.123.com
} else {
HTTP::redirect www.456.com
}
}
OR you can do the following:
when HTTP_REQUEST {
HTTP::redirect www.123.com
}
in your HTTP profile you specify a fallback host to be www.456.com.
The default pool of your VS will be poolA
This way if at least one pool member in poolA is available then this iRule will be executed and the the user will be redirect to www.123.com
fallback host in http profile specify a redirect to do in case all pool members are down
