Jul 26, 2012GTM DNS iRule
is it possible to use an iRule in GTM to make a decision about which IP to hand back based on the contents of the URL?
For example:
client 1 is in Singapore and wants to access a resource http://someapp.com/resource1
he is given IP 25.11.4.4
client 2 is in the US and wants to access a resource http://someapp.com/resource2
he is given IP 10.11.4.5
client 1 travels to US and tries to access his resource http://someapp.com/resource1
we want him to get IP 25.11.4.4
Is this possible?
Thanks,
Kevin

GTM doesn't know about URL's. It only knows about DNS requests. And only if the users have different LDNS (Local DNS) servers can GTM make a decision... When GTM gets the request, all it knows is the IP address of the client LDNS server. It doesn't know the clients actual IP address. So if your clients all happen to use the same DNS server, GTM has no way to know anything different about them.
