irule to call other irules?

Is it possible to have a master irule call other irules based on URI? Our dev teams want to control their own routing and not run the risk of breaking other apps. Example: We have three applications running. When you hit /app1, the main irule will see the URI as /app1 and load the /app1 specific irule. If you hit /app2, the main irule will load the /app2 irule. This prevents someone from putting /app1 rules in the /app2 irule. Is this even possible?

    Hello Brad.

    Actually, only iRule assigned to VS could be executed. So your idea of calling another iRules from a main iRule is not possible.

    ​

    Anyway, there is a way to isolate virtual hosts (app1, app2, ...) using VIP-targeting-VIP.

    ​

    The idea is to have a main VS which catches all the requests and redirects each request by app to another VS (using the "virtual" command).

    ​

    In this "new" virtual, you could assign another iRules that won't interfere with the rest of the VS.
