Hi,
You can't call one rule from another. You could combine the rules into a single rule. Or you could add the two rules to the virtual server and they will be triggered according to the priority (or if no priority is specified, then the order they're listed for the VIP). For details on priority, check the wiki page: (

As your rules look to be completely unrelated, you could keep the code in separate rules and add them to the VIP together. Priority in this case wouldn't matter as nothing in either rule would conflict with the other.
