reference a VIP's default pool within iRule?

I have an iRule that I want to use with different VIPs where each VIP may have a different default pool specified in the VIP configuration.

 

 

I'm wondering if I can generically reference the default pool within the iRule, so it will send traffic to different pools depending on which VIP calling the iRule.

 

 

I.E.:

 

 

when HTTP_REQUEST {

 

switch -glob [HTTP::path] {

 

"/abc/proxy.jsp" {

 

pool default <--the default pool for the VIP to which this iRule is applied

 

}

 

"/xyz*" {

 

pool xyz_pool

 

}

 

...

 

default {

 

pool def_pool

 

}

 

}

 

}

 

 

Thanks,

    You can use [LB::server pool] in CLIENT_ACCEPTED to get the name of the virtual server's default pool before it's change in the iRule: 

    
when CLIENT_ACCEPTED {

    Save the name of the virtual server's default pool before it's change in this iRule
   set default_pool [LB::server pool]
}
when HTTP_REQUEST {
    switch -glob [HTTP::path] {
        "/abc/proxy.jsp" {
            pool $default_pool
        }
        "/xyz*" {
            pool  xyz_pool
        }
        ...
        default {
          pool $default_pool
        }
    }
}
