Getting default pool associated with Virtual

Unruley suggested this a few times starting a while back:

You can try the following modifications to your rule to save the default pool and reuse it, thus generalizing your rule to be used with many virtuals.

 

 

rule cookie_lbsid {

 

when CLIENT_ACCEPTED {

 

set defpool [LB::server pool]

 

}

 

...

1) 9.1 does support the [LB::server pool] command which will return the currently selected pool. You do not have to wait until LB_SELECTED to get the currently selected pool. Thus something like this will return the original default pool on the virtual server:

 

 

when CLIENT_ACCEPTED {

 

if {not [info exists default_pool]} {

 

set default_pool [LB::server pool]

 

}

 

}

 

 

 

 

I think a lot of people have been using it since then to get the default pool of the VIP before any changes to the pool have been made on the connection.
