    Hello,

    For the good news, there's nothing complex here, just look into Local Traffic Policy feature. Both requirements can be fulfilled. Since your web-server already can distinguish between two different apps due to its own Web Server listener configuration, your BigIP configuration can be done with a single LTM pool.

    Test in your lab or staging environment the following:

    1 Virtual Server/1 Local Traffic Policy/1 LTM Pool/2 ASM policies

    Local Traffic Policy Logic:

    • Default Rule and Action - Select 
      ASMpolicy1
    • Conditional Rule and Action - If HTTP path starts with 
      /app2
      , select 
      ASMpolicy2

    LTM Pool:

    • LTM Pool is just mapped as Default Pool in Virtual Server configuration

    Regards,

Virtual Server - Resources - Policies
. Here you map that Local Traffic Policy which selects ASM policy based on best-match criteria. And you only need one Local Traffic Policy not two.

If you have mapped your Virtual Server to ASM policies in other ways, those should be removed. This includes the default Local Traffic Policy that is created when you first create your ASM policy as per standard procedure.
