App issue with GSS and F5 fail over

Scenerio is I have some internet facing reverse proxy web servers making calls to a cname on my GSS to resolve either the active or passive vip address on my F5's in two locations. This works as I now have in place a rule for the GSS to discard packets if no pool members are availible. The issue is when fail over occurs on the GSS the VIP address is still cached in my reverse proxy internt facing web servers and the only way for the Application to fail over in the upper layers is to recycle the services on the reverse proxies. This of course defeats teh purpose of using this config as manual intervention is needed. I was wondering if I can make the rule to dirgard the packet from the GSS and send the reverse proxy url request to the remote f5. Here is my script for the GSS fail over.

 

 

when CLIENT_ACCEPTED {

 

if { [active_members pool1] == 0 } {

 

discard

 

}

 

}

 

 

So I guess I would need to specify the source IP addresses of the packets from the GSS to read this rule and anything else to be redirected to the remote VIP"F5"?????
