outbound traffic for specific url by using specific IP

Sorry that was not clear. To clarify: - You cannot use that iRule on an IP forwarding VS, because you cannot apply an http profile to it. - On a standard VS, where you can apply that iRule, you need a pool to serve http traffic from, or the iRule needs to implement transparent proxy behavior... Oh, this is a request for google.com, let's resolve that name in DNS, then lets get this request answered from that server.

Makes sense?

Thanks, Mohamed.
