Is there a way to have two when condition statements in the same iRule.
I.e.
I am happy using this statement for regional IP source redirects
when CLIENT_ACCEPTED { if { [IP::addr [IP::client_addr]/24 equals 10.223.34.0] } { pool gw-pool member 10.223.32.1 } elseif { [IP::addr [IP::client_addr]/24 equals 10.236.36.0] } { pool gw-pool member 10.223.36.1 } else { Your other conditions, if necessary }}
But I would love to add a LB_Failed in there too!
so the logic would be when IP is acknowledged before redirecting to local gw-pool member check if gw-pool member is up if not send elsewhere.
- You can have as many event handlers (when statements) in your iRule as you wish.
when HTTP_REQUEST { do something } when HTTP_RESPONSE { do something }
In fact, you can have mulitple duplicate events in the same iRule (as long as you specify a different priority for them.)when HTTP_REQUEST priority 100 { do something } when HTTP_REQUEST priority 200 { do something else }
The default priority for an event handler is 500. Valid values are 0 to 1000 and they are processed from lowest to highest.

deantotham_2141Thanks Joe, I have subsequently spoken to a F5 engineer and was given a run down of the Topology feature which is what I was looking for which works in conjuntion with Health Checks.
